G(x)=(x+3)2 we must find x? so x+3=0 x=-3 we transformation -3 on left
80 inches or feet.. I think you are suppose to multiply 40x2 sorry if im wrong
<span>y=-3x²-30x-27
Δ=b²-4ac=(-30)²-4.(-3).(-27)=900-324=576 ∴ √Δ=24
x'=(-b

√Δ)/2a=(-(-30)

24)/2.(-3)=-54/6=-9
x''=</span><span>(-b-√Δ)/2a=(-(-30)-24)/2.(-3)=-6/6=-1
Raízes são
x''=-9 e x''=-1</span>
Step-by-step explanation:
First no. is 12
Second no. is 8
Third no. of 25
Way 1 of grouping the numbers,
(12×8)×25
We can use associative law of multiplication as follows :
(a×b)×c = a×(b×c)
(12×8)×25 = (96) × 25
= 2400
Way 2,
12×(8×25) = 12 × 200
= 2400
Way 2 is easier to simplify because when we multiply 8 and 25, we get 200. It is very easy to multiply any number with a number that have zeroes. As a result we easily get the answer i.e. 2400.
The answer is 2.5
hope this helps you out
