Answer:

Step-by-step explanation:

Remark

f(x) = 9x^2 - 5x + 3 is given. The notation means that wherever you see and x on the right, you replace it with the x in the brackes on the left. f(3) is a direction, not anything you have to adjust or manipulate.

Solution

f(-3) = 9*(-3^2) - 5*(-3) + 3       (-(3))^2 = -3 * -3 = 9  two minuses make a +

f(-3) = 9*(-3)(-3) + 15 + 3          -3 times an operation of minus equals a +

f(-3) = 9 * 9 + 15 + 3

f(-3) = 81 + 15 + 3

Answer: f(-3) = 99

Something that you should remember is that the sum of the angles of a triangle add up to 180°.

Since we are given 100° and that the other two angles are equal, we can set up an equation like this:

180=100+2x, where x is the 2 angles.

Doing the math, the measure of each unknown angles is 40°.
