X = 7 
Y = 16

Since we know that the bottom two sides are congruent we can make an equation to solve for that X first [2x + 5 = x + 12] .  (since we cannot make an equation with the two congruent sides at the top because there are different variables). 
Now that we've solved for X which is 7, we can plug it into the top equation [y - 4 = x + 5] which would simplify to [ y - 4 = 12] which would give us 16 for Y<span />

Question 2 Please
NeX [460]

Answer:

Step-by-step explanation:

Start by moving the 3 to the other side of the equals sign to get

tan^2(2\theta)=3

tan^2(2\theta)=(tan(2\theta))(tan(2\theta)) so with that replacement:

(tan(2\theta))(tan(2\theta))=3

By the Zero Product Property,

tan(2\theta)=3 or tan(2\theta)=3

Yes these are both the same, so we only need one of them.  Once we find the angle, they are both the same, so we only need one of these equations.

If

tan(2\theta)=3, take the inverse tangent of both sides to give you:

2\theta=tan^{-1}(3) and

2\theta=71.565 so

\theta=35.8

Tangent increases in increments of pi or 180, so the other angle within the given interval is 35.8 + 180 = 215.8

Expand and simplify the following:
il63 [147K]

Answer: 2d³+11d²+19d+10

Step-by-step explanation:

Use the FOIl method to simplify this

  • First
  • Outer
  • Inner
  • Last

-------------------------------------------------------------------

 (5+2d)(2+3d+d²)

=10+15d+5d²+4d+6d²+2d³ ⇔ Expand using FOIL

=2d³+(5d²+6d²)+(4d+15d)+10 ⇔ Put like terms together

=2d³+11d²+19d+10 ⇔ Combine like terms

Hope this helps!! :)
