The first step to factorize is to find the common terms. In this 5a is common throughout. By taking it out we get the expression:
5a (3 a^2 -b)
Hope this helps!
For that problem, all you have to do is add all of the trees up together. :3
It forms a right triangle.
To find X you can use the Pythagorean theorem which would be written as x^2 = a^2 + b^2
This can be rewritten as x = sqrt(a^2 + b^2)
Using the dimensions of the tree the answer would be :
B. x = sqrt(8^2 + 13^2)
Answer:
G=39, F=141
Step-by-step explanation:
Let us set up equations, with G and F as variables.
Since G and F are supplementary, they must add up to 180.
G+F=180
Given the equation, we can set it up too
F = 4 * G - 15
Here, we can solve for this equation by plugging the second equation into the first one with substitution
G+4*G-15=180
simplify and solve
5G=195
G=39
Plug this into the first equation to solve for F:
39+F=180
F=141
We can plug both answers into the second equation to check and find that we are indeed right.
