Answer:
A) 
Step-by-step explanation:
Given expression:

To factor the given expression completely.
Solution:
In order to factor the expression, we will factor in pairs.

We will factor the G.C.F of the terms in the pairs.
G.C.F. of
and
can be given as:


Thus, G.C.F. = 
G.C.F. of
and
can be given as:


Thus, G.C.F. = 
The expression after factoring the G.C.F. pairs is given as:

Taking G.C.F. of the whole expression as
is a common term.

The expression is completely factored.
Answer:
<h2>The angle ABC is 70°.</h2>
Step-by-step explanation:
You can observe a representation of the problem in the image attached.
According to the inscribed angle theorem, the angle created by two chords is half of its subtended arc, that means

Now, observe that the arc AC has as central angle the angle ABC, according to the theorem, the subtended arc and its central are congruent.

Therefore, the angle ABC is 70°.
Using quadratic formula you can have a maximum of two solutions. When you set this problem equal to zero, your a=-1, b=-10, c=2

I want to find the amount of antifreeze in a 15 quart solution with 30% antifreeze
<span><span>V<span>Antifreeze</span></span>=15∗0.30</span> =18/4 quarts of antifreeze
Similarly, I want to find the amount of antifreeze in a 15 quart solution with 35% antifreeze first.
<span><span>V<span>Antifreeze</span></span>=15∗0.35</span> = 21/4 quarts of antifreeze
<span>the difference between 21/4 and 18/4 is 3/4 quarts, which is the amount of pure antifreeze I've added in.

SO the V_fluid I replaced with 3/4 quarts of antifreeze is (3/4)/ 0.35</span>
