Answer:
x = , x =
Step-by-step explanation:
Given
4x² - 16x = 16x - 39 ( subtract 16x - 39 from both sides )
4x² - 32x + 39 = 0
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term, that is
product = 4 × 39 = 156 and sum = - 32
The factors are - 26 and - 6
Use these factors to split the x- term
4x² - 26x - 6x + 39 = 0 ( factor the first/second and third/fourth terms )
2x(2x - 13) - 3(2x - 13) = 0 ← factor out (2x - 13) from each term
(2x - 13)(2x - 3) = 0
Equate each factor to zero and solve for x
2x - 3 = 0 ⇒ 2x = 3 ⇒ x =
2x - 13 = 0 ⇒ 2x = 13 ⇒ x =
Answer:33 unit sq.
Step by step.
As we can see it is combination of three rectangles having two same small rectangkes so area of small rectangle is 2(2×3) is 12
Bow for bigger rectangle it is (7×3) is 21
so total area is 33 sq. unit
