∠a and ∠b are supplementary angles. if m ∠a =(x +6)° and m ∠b= (7x +30)°, then find the measure of ∠a.

24 Degrees

Step-by-step explanation:

Supplementary Angles are two angles with a sum of 180 degrees.

x+6+7x+30=180

8x+36=180

8x=144

18=x

Plug in 18 to angle A

18+6=24

24 degrees

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
