Please help with what goes in these blanks

See bold face answers below.

Step-by-step explanation:

If c^2 = a^2 + b^2, then the triangle is a right triangle.

If c^2 > a^2 + b^2, then the triangle is an obtuse triangle.

If c^2 < a^2 + b^2, then the triangle is an acute triangle.

Always keep "c" on the left side to avoid confusion when classifying.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
