Answer:
what kind of math is this?
Step-by-step explanation:
15:20
divide each by 5
3:4
to find the ratio of the area's we square the ratio's of the sides
3^3 : 4^2
9:16
Choice B
Answer:
Step-by-step explanation:
a² - b² = (a+ b)(a - b)
1) (2n-4/2n) ÷ (n^2-4/n)

2) [y^2-36/y^2-49] ÷[ y+6/y-7]

3) [m^2-1/ m^2-m] ÷ [m^2-7m-8/3m
]

Hint : m² - 7m - 8
sum = -7
Product = -8
Factor = (-8), 1
m² - 7m - 8 =m² - 8m + m - 8
= m*(m - 8) + (m-8)
= (m - 8)(m +1)
Answer:
-18+9k
Step-by-step explanation:
If you use the distributive property, you get:
(-3*6) and (-3*-3k)
If you simplify each of them you get:
-18+9k
Answer:
Increasing
Step-by-step explanation:
The computation is given below:
Given that
y = 74 × (1.01)^8
= 74 × 1.082856706
= 80.1314
As it can be seen that the initial amount is 74 but after solving the given equation the value is increased as it shows 80.1314
Therefore it is increasing
