Wouldnt it be 7 bc 7*6 is 42
Answer:
-67
Step-by-step explanation:
2^3-(3*5^2)
simplify exponents
8-3*25
8-75
=-67
T=21+4.5X
21 is the original temp.
4.5 is the constant rate I got when I subtracted 75-21=54 then divided 54/12min=4.5.
75 =21 + 4.5(12)
Ie 32^2 - 4ac=0 so ac=256 and a+c=130
So, that means:2 equations ac=256 a+c=130 ie c=130-a
So,a(130-a)=256 so 130a -a^2=256 ie a^2-130a +256=0 (a-2)(a-128)=0
Finally,giving a= 2 or a=128 so, a=2 c=128 or a=128 c=2
Since, a>c , a=128 and c=2 ie (128,2)
2.00 * 8.5%, which is also 2.00 * 0.085
2.00 * 0.085 = 0.17
2.17 after sales
