To get the denominator you would have to multiply w+5 by w-4

And whatever you do to the denominator you have to do to the numerator

(w-3)(w-4)
w^2-3w-4w+12
w^2-7w+12

So your answer would be c

Find the value of y in the equation attached to this question

dlinn [17]

Answer:

y = 4

Step-by-step explanation:

1) Simplify $3^5$ to 243.

${9}^{y}=\frac{243\times {9}^{6}}{{27}^{3}}$

2) Simplify ${9}^{6}$ to 531441.

${9}^{y}=\frac{243\times 531441}{{27}^{3}}$

3) Simplify $243\times 531441$ to 129140163.

${9}^{y}=\frac{129140163}{{27}^{3}}$

4) Simplify ${27}^{3}$ to 19683.

${9}^{y}=\frac{129140163}{19683}$

5) Simplify $\frac{129140163}{19683}$ to 6561.

${9}^{y}=6561$

6) Convert both sides to the same base.

$9^y=9^4$

7) Cancel the base of 9 on both sides.

$y=4$

Can anyone help me with this question please

Answer:

7. ∠CBD = 100°

8. ∠CBD = ∠BCE = 100°; ∠CED = ∠BDE = 80°

Step-by-step explanation:

7. We presume the angles at A are congruent, so that each is 180°/9 = 20°.

Then the congruent base angles of isosceles triangle ABC will be ...

∠B = ∠C = (180° -20°)/2 = 80°

The angle of interest, ∠CBD is the supplement of ∠ABC, so is ...

∠CBD = 180° -80°

∠CBD = 100°

8. In the isosceles trapezoid, base angles are congruent, and angles on the same end are supplementary:

∠CBD = ∠BCE = 100°

∠CED = ∠BDE = 80°
