Answer:
yes
Step-by-step explanation:
175 + 263 = 438
to get 40% do 40/100=0.4
so 438 x 0.4 = 175.2
175 is about 40% of 438
-2(v-2)=-3-2v doesn't have a solution
Answer:
0
Step-by-step explanation:
Substitute the given values for a and b into the expression
(18 + 14) - (18 - 14)²
=
× 32 - 4²
= 16 - 16
= 0
You would have to estimate this and a rough estimate would be around 240
