Answer:
15 m
Step-by-step explanation:
First split the shape into a square and a triangle, then find the area of the square by multipliyng the sides to get.
Next find the length of the traignel by subtracting 3 from 9 to get for then find the area of the triangle by multiplying 4 by 3 to get 12 then divide by 2 to get the area which is 6.
Finally add the 9 to the 6 to get 15
3 * 3 = 9
9 - 3 = 4
4 * 3 = 12/2 = 6
6+9=15
Dang this is too much to read i nearly understand the question
For the linear system :
r+t = 20 and 5(r+t) = 150
If you sub in the first equation into the second, you will get: 100 = 150, which is incorrect
It means the system does NOT have solutions.
Answer will be the last choice
9(9n-5)
9=0 9n-5=0
9n=5
9/5 is the answer and 0 or 9(9n-5)
Step-by-step explanation:
if I understand this correctly than you are looking for the inverse function of f(x) = y = 3x³.
the inverse function simply tries to calculate the original x it of the original y.
and then, to make it a formal function, we rename x to y and y to x.
y = 3x³
x³ = y/3
![x = \sqrt[3]{ \frac{y}{3} }](https://tex.z-dn.net/?f=x%20%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7By%7D%7B3%7D%20%7D%20)
=> as "regular" function
![y = {f}^{ - 1} (x)= \sqrt[3]{ \frac{x}{3} }](https://tex.z-dn.net/?f=y%20%20%3D%20%20%7Bf%7D%5E%7B%20-%201%7D%20%28x%29%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7Bx%7D%7B3%7D%20%7D%20)
