Answer:
64 : 729
Step-by-step explanation:
Ratio of surface area
= (ratio of linear dimensions) ^2
= 1.6^2 : 5.4^2
= 256 : 2916
= 64 : 729
Answer:
-76

i think this is rhigt
Answer:
Step-by-step explanation:
IVT --> If two points have a known y-value(one positive and one negative) and a known x-value, there has to be at least one real zero in between those two x-values. (assuming f(x) is continuous)
f(-4) = -64+16+8+19 = -21
f(-1) = -1+1+2+19 = 21
Conclusion: Since the -4 and -1 produce a postive y and negative y, there has to be atleast one zero in between.
Step-by-step explanation:
l = 3x - 5
w = 2x + 9
perimeter = 2l + 2w = 2(3x - 5) + 2(2x + 9) =
= 6x - 10 + 4x + 18 = 10x + 8
area = l×w = (3x - 5)(2x + 9) = 6x² + 27x - 10x - 45 =
= 6x² + 17x - 45
Answer:
I cant graph it but here’s how to solve for x
Step-by-step explanation:
Y=2x+1
-1 -1
—————
y=1x+ 0
y=x or y=1x
