Answer:
7x^2 -5x + 4
Step-by-step explanation:
5x^2 – 6x+2
- (-2x^2 - x - 2)
We got 5x^2 - (-2x^2) = 5x^2 + 2x^2 = 7x^2
-6x - (-x) = -6x + x = -5x
2 - (-2) = 2+2 = 4
So the equation would be 7x^2 -5x + 4
Hope this help :3
Answer:
18 miles
Step-by-step explanation:
Find how many miles he walked this week by multiplying 2 by 6:
2(6)
= 12
Add this to 6, since he walked 6 miles last week:
12 + 6
= 18
So, in all, he will have walked 18 miles
So normally it is
if 8x is to 6y, then how many x is to 42y?
it could be
if 8x:6y then how many x:42y or
if 8x:6y then how many y:42 x
I will solve for both
if it is
x:42y go to AAAAAAAA
if it is
y:42x then go to BBBBBBBBBB
AAAAAAAA
how many concerts are equal to 42 symponies
arrange in concerts to symponies format
8:6=x:42
fractionify
8/6=x/42
multiply boht sides by 42
336/6=x
56=x
56 concerts equals 42 symponies
BBBBBBBBBB
how many symponies are equal to 42 concerts
areange in symponies:concerts
6:8=x/42
fractionify
6/8=x/42
multiply boht sides by 42
252/8=x
31.5=x
31.5 symponies to 42 concerts
so it could be
56 concerts to 42 symponies
or
31.5 symonies to 42 concerts
