Answer:
Answer is – 3
Step-by-step explanation:
expand the expression using ( a – b) ( a + b) = a² –b²
( 3 ) ² – ( 6) ² *remember to place your square roots inside the brackets my phone doesn't have one*
then simplify the radical

Angle 0 is in standard position. if sin(0) = -1/3, < 0 < 3/2 , find cos (0).
Answer:
-2 sqrt (2) /3
Step-by-step explanation:
sin = -1/3 its in the 3rd quadrant so sin is negative cos is negative
sin^2 O + cos ^2 O = 1
1 - (1/9) = cos^2 O

In the attachment below I need you to find m∠DBC.
Answer:
m<DBC = 109
Step-by-step explanation:
8x-27=6x+7
8x=6x+34
2x=34
x=17
8(17)-27= 109
Answer: 109
Step-by-step explanation:
i'm not entirely sure of this answer as its been a while since ive done problems like this, however, i think the steps to solve are setting (8x-27) equal to (6x+7). Once you do that, you can solve for x. Substitute x into angle DBC to find the answer.
7(2- 6x) = -196 I having trouble understanding this problem.
Answer:
x = 5
Step-by-step explanation:
7(2 - 6x) = -196
14 - 42x = -196
14 - 42x - 14 = -196 - 14
-42x = -210
-42x/-42 = -210/-42
x = 5
Answer:
5
Step-by-step explanation:
7(2 - 6x) = -196 Remove the brackets
7*2 - 7*6x = - 196
14 - 42x = - 195 Subtract 14 from both sides
-42x = - 196 - 14
-42x = - 210 Divide by 42
x = - 210 / - 42
x = 5
9. Find the exact perimeter of a square whose side length is 5 cube root of 16.
Answer:
35.4 centimeters is your answer
80.5
The edges of a cube are called vertices, The inside of each square that takes up a cube is called, Area...So if the side length = 5 then you need to multiply 5x16 wich = 80 right and the length of each side is 5 so ad a decimal then a 5... btw if yur wondering 80.5 and 35.4 are equivalent
The required perimeter of the square with sides 5∛and 16 is 50.4.
Given that,
To find the exact perimeter of a square whose side length is 5 cube root of 16.
Perimeter is the measure of the figure on its circumference.
What is a square?A square is defined as a geometric shape that has four-sided and also a regular polygon
In the question, we have been given a side of square 5∛16 say a = 5∛16.
Now, the perimeter of a square is given as
The perimeter of the square = 4 a (where a is the side of the square)
= 4 * 5 ∛16
= 4 * 5 * 2∛2
= 50.4
Thus, the required perimeter of the square with sides 5∛and 16 is 50.4.

-((r-3-5p) How do I do this problem?
Answer:
-(-4P-3) =
4P + 3
Step-by-step explanation:
Answer:
5p - r +3
Step-by-step explanation:
Question shows - (r-3-5p)
- r - - 3 - - 5 p we can simplify and separate and instruct each value then add your brackets.
- r - ( - 3) - (- 5)
- r + 3 - ( - 5p) and see that the - - 5p = + 5p
-r + 3 + 5p then rearrange and keep format.
5p -r + 3
One garden had 5 times as many raspberry bushes as a second garden. After 22 bushes are transplanted from the first garden to the second garden, the number of raspberry bushes in the gardens are the same. How many bushes did each garden have originally?
Please show work and no links or files! :)
To solve this problem form the system of equations as per statements given in the question then get the answer by solving them.
Number of bushes in garden one were 55 and in second garden 11 originally.
Let the number of raspberry bushes in one garden = x
And the number of raspberry bushes in second garden = y
Garden one has 5 times as many raspberry bushes as second garden,So the equation for the given statement will be,
x = 5y -------(1)
22 bushes were transplanted from garden one to the second, number of bushes in both the garden becomes same,Therefore, equation for this statement will be,
(x - 22) = (y + 22)
x - y = 22 + 22
x - y = 44 ------(2)
Substitute the value of x from equation (1) to equation (2)
5y - y = 44
4y = 44
y = 11
Substitute the value of 'y' in equation (1),
x = 5(11)
x = 55
Therefore, Number of bushes in garden one were 55 and in second garden 11 originally.

The diagram shows a rectangle ABCD. The point A is (2, 14), B is (−2, 8) and C lies on the x-axis. Find
(i) the equation of BC,
(ii) find coordinates of C and D
Answer:
Step-by-step explanation:
since AB and BC are perpendicular so AB.BC=0, (scalar product)
AB=(-4, -6), and BC=(xc+2, yc-8)
AB.BC= -4x-8-6y+48 =0
so the equation of BC is 2x+3y-20=0
C is on the line BC, so 2xc+3yc-20=0, but yc=0, so xc=20/2=10
AB and CD are parallel, so det(AB, CD)=0
AB and AD are perpendicular so AB.AD=0
AB=(-4, -6) and CD =(x-10, y), AD= (x-2, y-14)
det(AB, CD)=0
x-10-y = 0 equivalent to x-y = -10
AB.AD=0
-4x+8-6y+84=0 equivalent to 2x+3y=44
let's solve
x-y = -10
2x+3y=44
-5y = -64, y = 64/5, x= -10+64/5=14/5
finally D(14/5, 64/5)

Find the unknown sizes of the angle
please answer fast
The opposite angles formed on an intersecting line are equal.
Here,
angle y + 10 = angle 2y - 80
Now,
y + 10 = 2y - 80
10 + 80 = 2y - y
90 = y
Therefore,
The angle y + 10 measures 100°.
Also, angle 2y - 80 measures 100°.
The other two angles measure 80° each.
A theater charges $4 for each matinee
ticket. If it sells 360 tickets for a matinee
performance, how much does it take in?
Answer:
1,440
Step-by-step explanation:
Because 360*4=1,440
Answer:
$1440
Step-by-step explanation:
What you're going to want to do is multiply 4 by 36 at first. This is going to get you to 144. If you really wanted to break it down, you can multiply 4 by 3, place a zero at the end, multiply 4 by 6, and add the totals. Next, since the question is 4x360 and not 36, we will need to place a zero at the end of the product. This will get you 1440. And so, the answer is $1440.
