Answer:
B. 100
Step-by-step explanation:
(m + n)^2
= m^2 + 2mn + n^2
Rearrange
(m^2 + n^2) + 2mn
Substitute
(68) + 2*16
= 68 + 32
= 100
Answer:
x=19
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
You have a total area of 2,200 sq units to cover... and each can of paint covers 400 sq units. So, you'll need:
2200 sq units / 400 sq units/can = 5.5 cans
In such problems, we always round up, since you will need 5 full cans of paint, and half of a 6th can.
So, in total you will need 6 cans of paint to cover all 2,200 sq units.
So 45% OF 40 is
45% * 40
0.45 * 40
that is 18
18 is 18% of what number?
18 = 18% * x
18 = 0.18 * x
divide both sides by 0.18
100 = x
45 % of 40, which is 18, and is 18% of 100.
Hope this helps
I’m pretty sure the answer is y = x - 2. If not then sorry..
