Answer:
h = 5
Step-by-step explanation:
area = 1/2 base × hight
base = 3 +h
hight =9 + 6 = 15
60 = 1/2 × 15 × (3+h)
120/15 = 3 + h
8 = 3 + h
h = 5
Answer:
h = 5
Step-by-step explanation:
The value of h can be obtained by using area of triangle formula as well as distance formula.
[tex]A(\triangle ABC) =\frac{1}{2} \times AB\times AC \\ \\ 60 = \frac{1}{2} \times \sqrt{ {( - 3 + 3)}^{2} + (9 + 6) ^{2} } \\ \times \sqrt{ {(h + 3)}^{2} + {(9 - 9)}^{2} } \\ \\ 60 \times 2= \sqrt{ {( - 0)}^{2} + (15) ^{2} } \\ \times \sqrt{ {(h + 3)}^{2} + {(0)}^{2} } \\ \\ 120= \sqrt{ 0 + (15) ^{2} } \times \sqrt{ {(h + 3)}^{2} + 0 } \\ \\ 120= \sqrt{ (15) ^{2} } \times \sqrt{ {(h + 3)}^{2} } \\ \\ 120 = 15(h + 3) \\ \\ \frac{120}{15} = h + 3 \\ \\ 8 = h + 3 \\ \\ h = 8 - 3 \\ \\ h = 5[/tex]

i need help please, this question has been giving me a headache.
Answer:
The first box (upper left corner)
Step-by-step explanation:
Since the y-intercept is 1/4 (you can find this where x = 0), in slope intercept the second number must equal the y-intercept.
Example:
y = 3x + 2 (0,2) is the y-intercept.
Therefore, the second number must equal 1/4 which the first box is correct.
(Negative 1/4 multiplied by -1 equals positive 1/4)

Can you solve x2-x-20=0 in algebra 1 explanation .
Answer:
x = 5, -4
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Answer:
x = 5, x = -4
Explanation:
Solve with the quadratic formula
[tex]x_{1,2} =\frac{-(-1)+-\sqrt{(-1)^2-4*1*(-20)} }{2*1}[/tex] = [tex]x_{1,2} = \frac{-(-1)+-(9)}{2*1}[/tex]
Separate the solutions
[tex]x_1 = \frac{-(-1)+9}{2*1} , x_2 = \frac{-(-1)-9}{2*1}[/tex]
[tex]x_1 = 5\\x_2 = -4[/tex]

7(-9a-3)-2a7(−9a−3)−2a
Hello!
To solve this, you need to distribute and combine like terms.
Like terms are equivalent types of numbers for example;
2x and 3x are like terms, so if the equation said 2x - 5 + 3x, you would only combine 2x and 3x.
If the equation said 5 + 9 - x, you add the like terms, 5 + 9, and the simplification would be 14 - x.
Distribution is when you multiply the number outside the parenthesis into the parenthesis. for example, if an equation says, 5(x-2) = y, you would multiply 5 on the numbers x and -2, resulting in the equation, 5x - 10 = y.
--------Now lets work on your math problem.
Step 1, right the equation, 7(-9a-3)-2a7(−9a−3)−2a
Step 2: distribute numbers (remember multiplying)
7(-9a-3)-2a7(−9a−3)−2a
For the first distribution, 7(-9a-3)-2a7(−9a−3)−2a
you multiply 7 to the numbers in the parenthesis,
resulting in,
-63a - 21
Second distribution is, 7(-9a-3)-2a + 7(−9a−3)−2a
in which you multiply -7 into the numbers in the parenthesis resulting in;
-63a - 21
(did you type the equation twice if so, there are now two problems i need to solve.)
now add like terms -2a + -2a = -4a
-63a - 21 + -63a - 21 = -126a - 42
-126a - 4a - 42
Answer is -130a - 42.
If your equation was actually this, : 7(-9a-3)-2a
Then the answer would have been, -65a - 21

Given F is the midpoint of EG. FE is 6x + 7 and EG is 18x - 4. What is the value of x?
Mid point of a segment divides the segment in two equal parts.
Value of x is 3.
It's given in the question,
EG = (18x - 4)F is the midpoint of EG.Therefore, EF = FG = (6x + 7)
And EF + FG = EG (By segment addition postulate)
Now substitute the values in the expression
(6x + 7) + (6x + 7) = (18x - 4)
12x + 14 = 18x - 4
12x - 18x = -14 - 4
-6x = -18
x = 3
Therefore, the value of x is 3.

If Mary has 12 more mangoes than Jason and Jason has y mangoes how many has Mary?
Answer:
y+12=m
Step-by-step explanation:
m (marys mangos)
Answer:
Mary's mangoes = y + 12
Step-by-step explanation:
Let's assume that,
→ Mary's mangoes = x
→ Jason's mangoes = y
The information given,
→ Mary has 12 more mangoes than Jason and Jason has y mangoes.
Now we have to,
→ find the mangoes Mary has now.
Forming the equation,
→ Mary's = Jason's + 12
→ [ x = y + 12 ]
Hence, the answer is x = y + 12.
42 POINTS PLEASE ANSWER.....The sum of the angles in a triangle is 180 degrees.In a particular triangle the first angle is 18 degrees less than the second angle, and the the third angle is 70 degrees. Write and solve an equation to find the measure of the first angels.
Answer:
46
Step-by-step explanation:
180-70=110
now we can take a guess on the other two. What two numbers added up make 110 and are 18 apart? 46 and 64 have 4 and 6. That makes 10. So now I know that the first and second angles are 46 and 64. According to the question, the first angle is smaller. So the first angle is 46.
Answer:
first angle = 46 and the second angle = 64
Step-by-step explanation:
(x,x-18,70)
x+x-18+70=180
2x+52=180
2x=180-52
2x=128
x=64
(x+x-18+70) since x is 64 replace;
x=64
x-18= 64-18= 46

22. Jesse's fish hook was 12 feet below the top of the water. He let out
some of his line, and the hook sunk another 3 feet. What is the depth of the
fish hook now? Write an addition problem, and then give the answer.
9514 1404 393
Answer:
15 ft below the top of the water
Step-by-step explanation:
We can let distances "below the top of the water" be represented by negative numbers. Then the initial height of Jesse's hook was -12 ft. Adding line allowed his hook to sink further:
-12 +(-3) = -15
The depth of Jesse's hook now is 15 feet below the water surface.
