Answer:
A
Step-by-step explanation:
if x=19, 19x3 =57 and 57+123=180 and straight angle = 180 so A
Answer:
X=19
Step-by-step explanation:
123 and 3x are supplementary/they equal 180 added together.
Let's solve your equation step-by-step.
123+3x=180
Step 1: Simplify both sides of the equation.
3x+123=180
Step 2: Subtract 123 from both sides.
3x+123−123=180−123
3x=57
Step 3: Divide both sides by 3.
3x/3 = 57/3
x=19
Have a splendid day.

Which of the following correctly completes the square for: x^2+2x=48
A. (x+2)^2=52
B. (x+1)^2=49
C. (x+2)^2=47
D. (X-1)^2=26
Answers
Answer:
(x+1)²= 49, the answer is B
Step-by-step explanation:
x² + 2x = 48
x² + 2x + (2/2)² - (2/2)²= 48 --[what we are trying to do is to complete a square by adding (2/2)² - (2/2)²]
(x+1)²= 49, the answer is B
Answer:
hey I'm pretty sure it's B. (x+2)²=49

The equation a = 26w gives the area of a (in square feet) of a rectangle dance floor with a width of w feet help please this is hard
Answers
Answer:
26ft
Step-by-step explanation:
Complete Question:
The equation a = 26w gives the area of a (in square feet) of a rectangle dance floor with a width of w feet. Find its length
Formula for calculating the area of a rectangle is expressed as shown;
Area of a rectangle = Length * Width
Given the equation a = 26w that gives the area of a rectangle
On comparing with the formula;
Length * Width = 26w
Length = 26ft (by comparison)
Hence the length of the rectangle is 26ft
Ren built a birdhouse with a volume of 224 in.3 Find the height of the birdhouse.
Answers
Complete question:
Ren built a birdhouse with a volume of 224 in³ Find the height of the birdhouse. A square pyramid. The square base has side lengths of 8 inches and the height is unknown.
Answer:
the height of the birdhouse is 10.5 in.
Step-by-step explanation:
Given;
volume of the square pyramid, V = 224 in³
length of a side of the square base, a = 8 in
The volume of square pyramid is calculated as;
[tex]V = \frac{a^2h}{3} \\\\where;\\h \ is \ height \ of \ the \ birdhouse \ (Pyramid)\\\\a^2h = 3V\\\\h = \frac{3V}{a^2} \\\\h = \frac{3 \times 224}{8^2} \\\\h = 10.5 \ in[/tex]
Therefore, the height of the birdhouse is 10.5 in.

Step-by-step explanation:
The 3 angles lie on a straight line and have a sum of 180°, that is
15° + a + 38° = 180°
53° + a = 180° ( subtract 53° from both sides )

Are the following two expressions equivalent?
Explain how you know...
3(4-x)
6(x+2)-7x
Answers
Answer:
no, because the first=12-x
and the second=-1x+2
Step-by-step explanation:
Answer:
No, they are not equivalent.
Step-by-step explanation:
First, we simplify the two expressions.
3(4 - x) = 12 - 3x We multiply everything inside the bracket by 3.
6(x + 2) - 7x = 6x + 12 - 7x = 12 - x Using BODMAS/BIDMAS, we first multiply everything in the brackets by 6 and then simplify.
If we compare 12 - 3x to 12 - x, we can clearly notice that they aren't equivalent. If they were to be equivalent, they would have to be exactly the same values as each other. The 12 is common in both expressions, but the -3x and -x differ, therefore the following two expressions aren't equivalent.

Louis wants to carpet the rectangular floor of his basement. The basement has an area of 363 square feet. The width of the basement is 1 3 its length. What is the length of Louis's basement? The length is feet.
Answers
Answer:
the length is 33 feet
Step-by-step explanation:
The computation of the length is shown below:
Let us assume the length be x
So the width be 1 by 3 x
And the area is 363 square feet
So
As we know that
Area = length × width
363 = x × 1 ÷ 3 x
363 = 1 ÷ 3x^2
Now
363 × 3 = x^2
1089 = x^2
x = 33 feet
hence, the length is 33 feet
