I think the answer would be 24 but im not 100% sure
Answer:
<u>The width of the rectangle is 6 cm and its length is 9 cm</u>
Step-by-step explanation:
Length of the rectangle = 3 cm greater than its width
Perimeter of the rectangle = 30 cm
Find the dimensions of the rectangle.
x = Width of the rectangle
x + 3 = Length of the rectangle
Now, let's solve for x, using the perimeter formula this way:
2 * width + 2 * length = Perimeter of the rectangle
Replacing with the values and variables we have:
2 * x + 2 * (x + 3) = 30
2x + 2x + 6 = 30
4x = 30 - 6
4x = 24
x = 6 ⇒ x + 3 = 9
<u>The width of the rectangle is 6 cm and its length is 9 cm</u>
Answer:
39x - 63
Step-by-step explanation:
5(3x - 3) + 4(6x - 12) ← distribute both parenthesis
= 15x - 15 + 24x - 48 ← collect like terms
= 39x - 63
Answer:
