Answer:y =
40 mi
Step-by-step explanation:
y = -.75(85) + 103.75
y = -63.75 + 103.75
y = 40 mi from home after 85 min
Hey there,
The question given is as follows:
- (3x² - 4x + 8) + (-x² - 2x - 8)
When we add polynomials we add like terms (e.x. we add 3x² with -x²) and combine the two to make one polynomial. When we add the two polynomials given above:
So our answer to the problem would be 2x² - 6x.
Hope I helped,

The answer there is the answer I got after figuring it out
I’m pretty sure you set the perimeters equal to each other, it would look like 3x+8+3x+7+3x = 3x+3x+4x+2 and then you add the similar ones so it would look like 9x+15 = 10x+2 then you subtract the two from both sides and subject the 9x from both sides and get 13 = x
AB would be 47
BC = 46
AC = 39
PQ = 39
QR = 39
PR = 54
then you could double check
47+46+39 = 39+39+54
132 = 132
