Answer:

Step-by-step explanation:

(7x)° + 61° = 180° (interior angle Postulate)

(7x)° = 180° - 61°

(7x)° =119°

7x = 119

$x = \frac{119}{7} \\ \\ \huge \red{ \boxed{x = 17}}$

If q(x)=7x^2-1 find q(-9)

liq [111]

For this, we are just going to plug in -9 for every x and then solve the equation:

$q(x)=7x^{2} -1$

$q(-9)=7(-9)^{2} -1$

$q(-9)=7(81)-1$

$q(-9)=566$

Now we know that q(-9) is equal to 566.

What is -√169? (note: negative in front of the √)

Mademuasel [1]

Hello!
Ignore the negative and solve the square root which is 13.
Add the negative with 13 you get -13
Special case is when it is square root of -169 then it will involved with i.
But for this question just solve it directly.
Have a great day!
