Answer:
The addidtive inverse is <u>7y²- x²y - 3xy + 7x²</u>
( here we need to change the sign of each of the term )
Answer:
A = 112 in²
Step-by-step explanation:
First, find the area of the square, which is 10 in. by 10 in.
10 × 10 = 100 in²
Next, find the area of the triangle using the formula: 1/2(base × height)
The base is 10 in. - 6 in. = 4 in.
The height is 16 in. - 10 in. = 6 in.
A = (1/2)(4 × 6) = (1/2)(24) = 12 in²
Add the two areas.
100 in² + 12 in² = 112 in²
Let's the length to be x,
then the width is 8x - 2.
Perimeter of a rectangle = 2*Width + 2*Length
Perimeter of the rectangle = 2(8x-2) + 2x = 16x - 4 + 2x = 18x - 4
Ar the same time, Perimeter of the rectangle = 88.
So, we can write
18x - 4 = 88
18x = 84
9x=42
x= 42/9 cm (length) or ≈ 4.67 cm (length)
8x - 2 = 8*42/9 - 2 ≈ 35.33 cm (width)
