<span>(a^2+b^2)^2
since (a+b)^2=a^2+2ab+b^2, substitute a with a^2 and b with b^2, which yields:
a^4+2(a^2*b^2)+b^4</span>
Answer:
7 inches
Step-by-step explanation:
I cant see the illustration, but I will assume it is a rectangle. The formula for the perimeter of a rectangle is P=2w+2l
let P represent the perimeter of the window in inches
let w represent the width of the window in inches
let l represent the length of the widow in inches
(L is l whereas one is 1)
So we know w=5 and P=24
This lets us have the equation 24= 2 x 5 + 2l
24=10 + 2l
14=2l
7=l
Answer:
29 units²
Step-by-step explanation:
You could divide this into two triangles and two trapezoids to find the area. But since the majority of these are either whole or half squares, I‘d count those. Then you’d just have one triangle in the top right corner.
Whole squares: 21
Half Squares: 10 (so 4 square units)
Triangle: 1/2(b)(h)=1/2(5)(2)=5
TOTAL = 21+4+5= 29 units²
Answer:
Step-by-step explanation:
-12 = 4(-6 + f)
-12 = (-6 * 4 + f * 4)
-12 = (-24 + 4f)
-12 = -24 + 4f
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Add '-4f' to each side of the equation.
-12 + -4f = -24 + 4f + -4f
Combine like terms: 4f + -4f = 0
-12 + -4f = -24 + 0
-12 + -4f = -24
Add '12' to each side of the equation.
-12 + 12 + -4f = -24 + 12
Combine like terms: -12 + 12 = 0
0 + -4f = -24 + 12
-4f = -24 + 12
Combine like terms: -24 + 12 = -12
-4f = -12
Divide each side by '-4'.
f = 3
Simplifying
f = 3
