Answer:
1936
Step-by-step explanation:
x² + 87 = (x +1)²
x² + 1)² - x² =87
(x² + 2x +1) = 87
2x + 1 = 87 ⇒ x = 44
44² = 1936
Answer:
length is 40 and breadth is 20
Step-by-step explanation:
120 =2( l + b )
120 = 2( 2x +x )
120= 2 x 3x
120 =6x
120/6 = x
20 = x
length=2x = 2 x 20 = 40
breadth= x = 20.
hope it helps u
Answer:
f(-1) = 121
Step-by-step explanation:
f(x) = (5-6x)^2 (First we will substitute x for -1)
f(-1) = (5-6(-1))^2 (Then we will combine like terms)
f(-1) = (11)^2 (Then we will square it)
f(-1) = 121 (You are done)
Step-by-step explanation:
you multiply the length time the width
the answer would be in cm^2
