Answer:
- D. 2x² + 10xy + 8x² because (2x+ 2y) by (x + 4y)
Step-by-step explanation:
Let's mark the sides of the big square as x and a small square as y
<em>See attached picture below</em>
<u>Then we will have the sides of the rectangle:</u>
- x + x + y + y = 2x + 2y
- and
- x + y + y + y + y = x + 4y
<u>The area of the figure is:</u>
- A = lw
- A = (2x+ 2y)(x + 4y)
- = 2x² + 8xy + 2xy + 8y²
- = 2x² + 10xy + 8x²
Correct option is D.
We know that HJ + JK = HK
So lets substitute each part for their equation.
(2x + 5) + (3x - 7) = 18
Combine like terms
5x -2 = 18
Add 2 to both sides to eliminate it
5x = 20
Divide both sides by 5
x = 4

Answer:
Given below
Step-by-step explanation:
The algebraic identity is (a-b)^2
= a^2 + b^2 - 2ab
So it'll be,
(x-4)^2
= x^2 + (4)^2 - (2)(x)(4)
= x^2 -8x + 16
or x^2 +16 -8x
