Answer:
the answer is 20
Step-by-step explanation:
The answer is 20. The rule of math, for this math problem, is that you do the multiplication first and then solve. Order of operations is "PEMDAS," which explained is by following these rules: Parentheses First.
Answer:
-4x - 24
Step-by-step explanation:
distribute the -4 by multiplying it by what is in the parenthisis. Since it is negative that makes a -4x and a -24
35
area of triangle is (base X height)/2
so it would be (14 X 5)/2
which is 70/2
which is 35
Answer:
x=2
Step-by-step explanation:
i would set up a system of equation using the pythagorean theorem:
1^2+x^2=z^2
4^2+x^2=y^2
Add up these equations to get:
17+2x^2=y^2+z^2
But notice that
y^2+z^2=5^2
So you can substitute
17+2x^2=25
2x^2=8
x^2=4
x=2
