Answer:
Scale factor is 2.5
Value of X: 27.5
Value of y: 12
Value of z: 7.5
Step-by-step explanation:
Okay so. A scale factor is the number by which the shape is increasing, or decreasing by. Like if a square went from 5 cm on all sides to 10 cm on all sides, the scale factor would be 2. This shape has been rotated, so you want to rotate it back so the sides match up when you compare them. The only two sides with a number (without a variable) are 8 and 20, for 8 to be able to get to the number 20, it had to be multiplied by 2.5. To get all the other sides answers, you need to multiply any numbers by 2.5 if it the shape of the left, if it is the shape on the right you need to divide it by 2.5.

Answer:
(5^4)^-3 = 4.096e-9
Step-by-step explanation:
Answer:
Step-by-step explanation:
Basically when a variable with a negative exponent, such as 
, you just take the reciprocal of it and then change the exponent sign, or in simple terms flip it. The reciprocal of a^{-2} and changing the exponent sign is is 
.
To demonstrate let’s solve the first problem:
Using what we just learned, we take the reciprocal and flip the sign of 
and 
, which are 
and 
respectively.
Therefore the equation is now:
To simplify we add the exponents (only if they have the same base, or the same variable, in this case)
Therefore our answer is:
