The length of a rectangle is 14 inches, and its area is ( + ) square inches. Factor the expression for the area.

The question is incomplete, the complete question is here

The length of a rectangle is 14 inches and it’s area is (42x + 56) square inches. Factor the expression for the area. Write an expression for the width

The factorization of the expression of the area is 14(3x + 4)

The expression of the width is (3x + 4) inches

Step-by-step explanation:

To factor an expression find the greatest common factor of the terms of the expression, then divide each term by it to find the reminder of the terms in the bracket

∵ The area of the rectangle = (42x + 56)

- Lets find the factors of 42 and 56

∵ 42 = 1 × 42 , 2 × 21 , 3 × 14 , 6 × 7

∴ The factors of 42 are 1, 2, 3, 6, 7, 14, 21, 42

∵ 56 = 1 × 56 , 2 × 28 , 4 × 14 , 7 × 8

∴ The factors of 56 are 1, 2, 4, 7, 8, 14, 28, 56

∵ The common factor of 42 and 56 are 1, 2, 7, 14

∵ The greatest one is 14

∴ The greatest common factor of 42 and 56 is 14

Divide each term of the expression of the area by 14

∵ 42x ÷ 14 = 3x

∵ 56 ÷ 14 = 4

∴ (42x + 56) = 14(3x + 4)

∴ The factorization of the expression of the area is 14(3x + 4)

∵ The length of the rectangle is 14 inches

∵ Area of a rectangle = length × width

∴ The width of the rectangle is (3x + 4) inches

∴ The expression of the width is (3x + 4) inches

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
