W+2 the answer is this because u figure out the factor of W
Well, I'm way past the 15 min mark, but here's how to do the question.
With this, you will need to use the distance formula,
, on XY, YZ, and ZX.
XY: 
Firstly, solve inside the parentheses: 
Next, solve the exponents: 
Next, solve the addition, and XY's distance will be √29
(The process is the same with the other 2 sides, so I'll go through them real quickly)
YZ:

ZX:

Now that we got the 3 sides, we can add them up: 
In short, your answer is 14.8, or the second option.
Which two numbers add up to <span>88</span><span> and multiply to </span><span>−20?
</span><span>−2</span><span> and </span><span>10
</span>
Rewrite the expression using the above:
Answer:
(a−2)(a+10)<span>

Answer:
The 3rd option
Step-by-step explanation:
To prove that 2 triangles are similar, we need to prove that 2 pairs of their angle measurements are congruent.
This is because all triangles have 180 degrees, so if 2 pairs are congruent, the remaining angles will also be congruent
We know that m<D=m<E
We also know that m<DCA=m<ECB because they are vertical angles.
Vertical angles are always congruent.
Therefore, the triangles are similar.
The correct similarity statement would be 1, since <D corresponds with <E.
Now let's look at the 3rd Statement. To prove that two lines are similar, we would have to prove that their alternate interior angles are congruent.
A pair of alternate interior angles would be <D and B or or <E and <A
There is no way to prove this, since we do not know any of the angle or that measurements or if the triangles are isosceles triangles.
Hence, the correct choice would be 1 only.
Your answer for m would be -4, as -4x9=-36, and -36+36=0
