Subtract 10x2 – 10x + 2 from - 8x2 + 7x – 7.

18x^2 - 17x +9

Step-by-step explanation:

Original equations:

10x^2 - 10x + 2

-8x^2 +7x - 7

Calculations:

10x^2 - (-8x^2) = 18x^2

(-10x) - 7x = -17x

2 - (-7) = 9

Together, they make: 18x^2 - 17x + 9

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
