Answer:
x = 17
Step-by-step explanation:
2+x = 2x-15
subtract x on both sides
2 = x -15
add 15 to both sides
17 = x
------------------
17+2 = 2(17)-15
19 = 34 -15
19 = 19
Answer:
Step-by-step explanation:
Because you can't do -x+1 so it would be (1,0) and then you have x^2 +3x-4 which is (-5,6)
The answer is C.
x=2
y=-30
(2;-30)
So we should first start off by checking for the ones with the same area, which is 72sq cm
80×90=7200sq cm so A is incorrect
8×10=80sq cm so B is incorrect
3×24=72sq cm so, so far C is correct
4×14=56sq cm so D is incorrect
And because all are incorrect except C
Then C is the correct answer, just to be sure, we will check the perimeter
24+24=48
48+3=51
51+3= 54
So the perimeter is different, making C the correct answer
