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
Answer:
c² - 63
Step-by-step explanation:
4c - 10 = 30
3c ÷ 3 = 10
c² - 63 = 37
c² ÷ 10 = 10
Since c² - 63 = 37 and c + 25 = 35, 37 is greater than 35 so it would make sense to choose c² - 63 as the answer.
c + 25 < 37
I hope this helps you :D
Hi there!
The substitutions are 10 and 0.
1) x = - 4 and y = 8
answer is d. last choice
2) x = 16 y =20
answer is d. last choice
3) x - 6y = -24
so -x + 6y = 24
answer is B. second choice
4) 4.75k + 2.25p = 22
answer is a. first choice
5) last graph.
answer is D.
