Done!!
Answer:
Step-by-step explanation:
12/30 = 0.4
percent is rquivalent to 12/30 : 0.4×100 =40
First option
y = 3(x+7/6)² - 25/12
1,280 it ez bro
C. -7x^2 - 28
Firstly simplify the bracket before doing anything;
4x(3x - 7) = 12x^2 - 28x
then go back to the question and substitute the expression(12x^2 - 28x) on the bracket and then work out the question;
12x^2 - 28x -19x^2...then group the values with the same exponent of x,
(12x^2 - 19x^2) - 28x
; -7x^2 - 28x
