Answer:
x = 4 or x = -10 for equation x^2 + 6x = 40
Step-by-step explanation:
x^2 + 6 = 40
x^2 = 40 - 6
x^2 = 34
x = root(34) or x = -root(34) but this is not in the answer choice.
is it x^2 + 6x = 40
x^2 + 6x + 9 = 40 +9
(x + 3)^2 = 49
x + 3 = 7 or x + 3 = -7
x = 4 or x = -10
Answer:
600
Step-by-step explanation:
Since 3/4 of 100 is 75, we have to divide 450 by three.
450 ÷ 3 = 150
150 x 4 = <em><u>600</u></em>

Remember to distribute invibile -1
simlify 2nd part
-(a^2-3a+7)=-1(a^2-3a+7)=-a^2+3a-7
now we have
3a^2+2a-2-a^2+3a-7=
3a^2-a^2+2a+3a-2-7=
2a^2+5a-9
