Answer:
f(-9)=31
Step-by-step explanation:
f(x)=-5x-14
f(-9)=-5(-9)-14
f(-9)=45-14
f(-9)=31
Use the property
(a -b)(a+ b) = a^2 - b^2
49x^2 - 81 = (7x + 9)((7x - 9)
Answer:
x = 17
Step-by-step explanation:
x and 163 are same- side interior angles and are supplementary, sum to 180°
x + 163 = 180 ( subtract 163 from both sides )
x = 17
