Let n = the unknown number
"The product of a number and 4" = 4 * n = 4n
"increased by 16" = + 16
Set it all equal to - 2.
4n + 16 = - 2
Subtract 16 from both sides to get constants on one side and variables on the other.
4n = - 2 - 16
Combine like terms:
4n = - 18
Divide both sides by 4 to isolate variable n.
n = - 18 / 4
= - 4 and 2/4 = - 4 and 1/2
Answer:
Step-by-step explanation:
The ratio of the sides is the same as the one-to-one measure of the similar figures. To get to the ratio of their areas, square the one-to-one values. To get to the ratio of their volumes, cube the one-to-one values.
If the one-to-one is 3:7, then the ratio of their volumes is
3³:7³ which is 27:343
Since you are working with exponents and roots you would add the exponents together. The ninth root of x is equal to x^(1/9) and since you are using it four times your answer would be x^(4/9).
