Answer:<u> x=-3</u>
<u></u>
Step-by-step explanation:
2x(3x+9)=-2(2x+6)
2/3 (3x)+2/3(9)=(-2)(2x)+(-2)(6) distrubute this
2x+6=-4x+-12
2x+6=-4x-12. subtract 4 on both sides
2x+6=-4x-12
2x+6+4x=-4x-12+4x
6x+6=-12
6x+6-6=-12-6
6x=-18
6x/6=-18/6
=x=-3
Hoped this helped sorry it took me forever:)
In the same way as you could factor trinomials on the form of
<span><span><span>x2</span>+bx+c</span><span><span>x2</span>+bx+c</span></span>
You can factor polynomials on the form of
<span><span>a<span>x2</span>+bx+c</span><span>a<span>x2</span>+bx+c</span></span>
If a is positive then you just proceed in the same way as you did previously except now
<span><span>a<span>x2</span>+bx+c=<span>(<span>x+m</span>)</span><span>(<span>ax+n</span>)</span></span><span>a<span>x2</span>+bx+c=<span>(<span>x+m</span>)</span><span>(<span>ax+n</span>)</span></span></span>
<span><span>where c=mn,ac=pq </span><span>and b=p+q=am+<span>n</span></span></span>
Let
l-------> the slant height of the right pyramid
b------> the length side of the square base of the right pyramid
h------> the height of the right pyramid
we know that
Applying the Pythagorean Theorem
Solve for h
in this problem we have
Substitute in the formula
therefore
<u>the answer is</u>
The height of the right pyramid is 
B. 2.9 m, 3.0 m, 3.1 m, 3.2 m
