So with this, we will be using proportions. To solve for x, our proportion will be 
Firstly, cross-multiply: 
Next, subtract 36 on both sides: 
Next, replace -9x with 3x-12x 
Next, factor x^2+3x and -12x-36 separately: 
. After, rewrite it as 
Next, solve for x separately in the two parentheses:
Since we can't have a negative length, x = 12.
To solve for y, our proportion will be 
Firstly, cross-multiply: 
Next, just square root each side, and your answer will be (rounded to hundredths) 
In short, x = 12 and y = 10.39.
8^2 = 8*8 = 64
3^3 = 3*3*3 = 27
2^4 = 2*2*2*2= 16
10^5 = 10*10*10*10*10 = 100000
Answer:
42
Step-by-step explanation:
Answer:
Similar
Step-by-step explanation:
There are two triangles in this picture, ABC and A'B'C'. Triangle ABC have 2 base and 2 height. Triangle A'B'C' have 6 base and 6 height, which is 3 times larger than ABC. When two objects have the same shape but different size, it is called similar.
A similar object can be made by using dilation transformation. In this case, ABC triangle have been dilated by 3 times to make A'B'C'
