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:
Ramp
Step-by-step explanation:
A ramp is easier for a person to go up or down on because it is just higher sloped ground. For a person with crutches, a ramp does not have any abnormal steps for them to try and get over with one leg.
0.0045 is the answer so if wrong
<span>4 ⋅ 6 + 5 ⋅ 7 + 6 ⋅ 8 + ... + 4n( 4n + 2) = 4(4n+1)(8n+7)/6
is false because it isn't even true when n=1.
4 ⋅ 6 = 4(4*1+1)(8*1+7)/6
24 = 4(5)(15)/6
24 = 50
Also 4n(4n+2) is not even the correct formula
for the nth term. The correct nth term formula
of 4 ⋅ 6 + 5 ⋅ 7 + 6 ⋅ 8 + ...
is (n+3)(n+5). So it's wrong all the way around.</span>
