Answer:
K=-89
Explanation:
K=10(-7)-19
We want to find the greatest common factor of two given expressions.
The GCF is 15*a*b.
The two expressions are:
45*a^3*b^2 and 15*a*b
To find the greatest common factor, we can rewrite the first expression to get:
45*a^3*b^2 = (3*15)*(a^2*a)*(b*b)
Now remember that we can perform a multiplication in any order we want, so we can rearrange the factors to write this as:
(3*15)*(a^2*a)*(b*b) = (15*a*b)*(3*a^2*b)
Then we have:
45*a^3*b^2 = (15*a*b)*(3*a^2*b)
So we can see that 15*a*b is a factor of 45*a^3*b^2, then the GCF between 15*a*b and 45*a^3*b^2 is just 15*a*b.

Answer:
<h2>486mm²</h2>
Step-by-step explanation:
The area of a parallelogram is h*b where h is the height/altitude and b is the base.
The base is 27 millimeters and the altitude is 18 millimeters, so we multiply those together.
27*18= 486.
The area of the parallelogram is 486mm²
