Answer:

Step-by-step explanation:
V=L×W×H
=3½in×1⅞×2¾
=3×2+1/2in × 1×8+7/8in × 2×4+3/4in
=7/2in × 15/8in × 24/4in
=2520/64 incube
so it's you tern to change into mixed fraction
sorry for that
but if it's helpful ❤❤
THANK YOU

Answer:
Step-by-step explanation:
So we can just set up a proportion
14.5/2=x/3
we can cross multiply
so that means
2x=43.5
x=21.75
Answer:
9. 6k + 5 and 2k - 1.
10. 5√2 .
Step-by-step explanation:
9. Area = 12k^2 + 4k - 5
Factoring:
12k^2 - 6k + 10k - 5
= 6k(2k - 1) + 5(2k - 1)
= (6k + 5)(2k - 1)
So the required lengths are 6k + 5 and 2k - 1.
10. The ratio of a leg to the hypotenuse is 1: √2 so if the hypotenus = 10 the length of a leg is 10 / √2
= 10 √2 / 2
= 5√2 .
