Write an equation for: 2 sides of a rectangle are the same length =r
The other side is 4 meters
The perimeter of the rectangle is 26 meters
Use the following numbers & r in the equation that equals 26
2. 4. 8. R. 26

m∠a is 90°

m∠b is 40°

4

step-by-step explanation:

might be the correct answer will be question number 2

a

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a
