Answer:
hope it will help you
Step-by-step explanation:
f(x)=x²+7
X(-2)=?
therefore X(-2)=(-2)²+7
=4+7
=11
Answer:
x=4-√79, x=4+√79
Step-by-step explanation:
Step-by-step explanation:
U = (x - 5)
V = y^3
because we follow the rule
(U+V)^2 = U^2 + 2UV + V^2
factor the expression will be
The answer would be 30% , 3% would only be correct if he gave 0.3/10
(-10) + 14 + 25 + (-16) Add 14 and 25
(-10) + 39 + (-16) Change 39 + (-10) to 39 - 10
(-10) + 39 - 16 Subtract 16 from 39
(-10) + 23 Change (-10) + 23 to 23 - 10
23 - 10 Subtract 10 from 23
13
*Remember, you can rearrange expressions like this as long as each number keeps its sign. Notice that (-10) had its negative sign the whole time, even though we moved it around.
