z+7-z+9
Step-by-step explanation:
Answer:
28
Step-by-step explanation:
in order to evaluate for the value of x from this 2(x+5)=7x-5 , we will open the bracket and the evaluate for x.
solution
2(x+5)=7x-5
2x + 10 = 7x - 5
collect the like terms together
2x + 10 +5 = 7x
15 = 7x - 2x
15 = 5x
divide both sides by 5
15/5 = 5x/5
3 = x
x =3
so, to evaluate for 2x² + 10
will be
2x² + 10
2 (3)² + 10
2 x 9 + 10
18 + 10

Answer:
14
Step-by-step explanation:
(a+b)^2
(a+b)(a+b)
FOIL
a^2 + ab+ab + b^2
Combine like terms
a^2 +2ab + b^2
Rearranging
a^2+b^2 +2ab
We know a^2+b^2 = 4 and ab= 5
4 + 2(5)
4+10
