You cant since you have no measurements
you realize you could easily go around the whole perimeter w/ a tape measurer then add the sides together
It changed 19 degrees. Since it's -13, you just count until you get -13.
Answer:
D.
Step-by-step explanation:
h(x)=f(x)g(x) means multiply the expression for f to the expression for g.
That is the problem is just asking you to do (11x-5)(-2x-4).
Let's use foil.
First: 11x(-2x)=-22x^2
Outer: 11x(-4)=-44x
Inner: -5(-2x)=10x
Last: -5(-4)=20
------------------------Add together!
-22x^2-34x+20
D.
Answer: 20%
<em>Step by Step Explanation: </em>
<em>Start by subtracting 519.29 from 649, you would get 129.8</em>
<em>Then take 129.8 and divide that by 649.</em>
<em>You get 0.2 which equals 20%</em>
<em>Tip: To find the percent of a fraction you divide the numerator by the denominator. For example, if you want to find the percent on a test, and you get a 8/10 you just divide 8 by 10. Which obviously equals 80.</em>
