Answer at the bottom
Step 1: Simplify both sides of the equation.
4x−7x=34−55
4x+−7x=34+−55
(4x+−7x)=(34+−55)(Combine Like Terms)
−3x=−21
−3x=−21
Step 2: Divide both sides by -3.
−3x
−3
=
−21
−3
x=7

Answer:
The answer is rotation 270° about the origin
Step-by-step explanation:
If (x , y) is a point in xy-coordinates
If the point rotate about the origin ⇒ (The positive direction is anti-clockwise)
1- 90°
Its image is (-y , x)
2- 180°
Its image is (-x , -y)
3- 270°
Its image is (y , -x)
If we assume A is (1 , 7)
1- ⇒ (-7 , 1) ⇒ rotation 90° about the origin
2- ⇒ (-1 , -7) ⇒ rotation 180° about the origin
3- ⇒ (7 , -1) ⇒ rotation 270° about the origin
∵ x-coordinate of point A small and +ve and y-coordinate large and +ve
∵ x-coordinate of point A' large and +ve and y-coordinate small and -ve
∴ The answer is rotation 270° about the origin
∴ The answer is rotation 270° about the origin
A radical expression has to do with finding the square root, or the factors of a number. However these factors are the same number, which is why a radical expression is different from a regular divisions equation. (hope this helped :) )
Answer:the length of the rectangle is 36 feet
Step-by-step explanation:
Let L represent the length of the rectangle.
Let W represent the width of the rectangle.
The length of a rectangle is equal to three times its width. This means that
L = 3W
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
If the perimeter is equal to 96
feet, it means that
2(L + W) = 96
L + W = 96/2 = 48
Substituting L = 3W into L + W = 48, it becomes
3W + W = 48,
4W = 48
W = 48/4 = 12
L = 3W = 3 × 12 = 36
