Answer:
27
Step-by-step explanation:
its 3 times 3 times 3
So, for this kind of problem you need to FOIL.
This stands for:
F- first
O-outer
I-inner
L-last
What this means is that:
step 1- multiply the FIRST terms in each thing. So for example in problem 6 of the problems you sent it would be x times x. =
step 2- multiply the OUTER terms in each thing. So for example in problem 6, it would be x times 3. =3x
step 3- multiply the INNER terms in each thing. So for example in problem 6, it would be 6 times x. =6x
step 4- multiply the LAST terms in each thing. So for example in problem 6, it would be 6 times 3. =18
step 5: you add all of your products. So for problem 6 it would be y=
+ 9x +18.
Find the missing side of the right triangle using Pythagorean Theorem:
10^2 =8.7^2 +x^2;
x^2=100-75.69=24.31
x= sqrt 24.31~ 4.93
Area of trapezoid is area of triangle+area of a rectangle.
A=(8.7x4.93/2)+(12x4.93)
A=80.6055 ~81 ft^2
Answer: x = 13
angel bge and angle agf are vertical meaning they’re equivalent
77 + 90 + x = 180 (180 because all of them added together are supplementary)
167 + x = 180
x = 13
