Answer:
a = 30
Step-by-step explanation:
a/ 50 = 3/5
Using cross products
a*5 = 50 *3
5a = 150
Divide each side by 5
5a/5 = 150/5
a = 30
(5x-7)2 + 140x
= 25x2 - 70x + 14 + 140x
= 25x2 + 70x + 14
= (5x+7)2

Answer:
3 cm
Step-by-step explanation:
The formula for the area of a rectangle is ...
A = LW . . . . . . area is the product of length and width
Fill in the given values and solve for the width (W).
18 cm² = (6 cm)W
(18 cm²)/(6 cm) = W = (18/6) cm²/cm . . . . . . divide by the coefficient of W
W = 3 cm
The width of the rectangle is 3 cm.
