What is the answer using order of operations? ?

(4^2 + 7) * 4 - 5 + 7

Parentheses first.

23 * 4 - 5 + 7

Multiplication.

92 - 5 + 7

Subtraction.

87 + 7

Addition.

94 is the final answer.

94!

Use P.E.M.D.A.S to figure this out. It stands for...

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

All you do is follow that order! First, solve the problem in the brackets, which is 23. So now you have 23 x 4 - 5 + 7.

23 x 4 = 92

92 + -5 + -7 is 94.

Hope this helps! Sorry its long. :)

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

step-by-step explanation:

mark brainliest!

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
