1. The value of x is 4. X + 4 = 4 + 4 = 8
Answer:
5:6
Step-by-step explanation:
To find the ratio of side lengths you need to cube root of the ratio of the volumes. The reason you use the cube root is because you are multiplying 3 things together when you find volume.
![\sqrt[3]{\frac{125}{216} } =\frac{5}{6}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B125%7D%7B216%7D%20%7D%20%3D%5Cfrac%7B5%7D%7B6%7D)
5 : 6
Answer:
x = - 8
Step-by-step explanation:
To solve for x, isolate it by "moving" everything else over to the other side. This is done in reverse BEDMAS order using the reverse operations of number you want to move.
3 (2x-1 ) +7 = - 44 Simplify first using distributive property over the brackets
6x - 3 + 7 = - 44 Combine like terms, terms that have the same variables
6x + 4 = - 44
6x + 4 - 4 = - 44 - 4 Subtract 4 from both sides to cancel it out on the left side
6x = - 48
6x/6 = - 48/6 Divide by sides by 6 to cancel out the 6 from 6x
x = - 8 Final answer
The area is 2x^2+x-10 (the last one) Hope this helps!
