I HOPE IT WILL HELP YOU. I DID HOW I KNOW .
Five-5
three-3
"the quantity five plus three" (5 + 3)
"one hundred times the quantity ..." means 100 (5 + 3)
now just solve 100(5+3)
solve the parentheses first (5+3) = 8
Now you are left with 100(8) or 100*8
when you solve your answer is 800
So you want to find two numbers that add up to -13 and multiply to
40. You can find the factors of 40 and find the pair that adds up to
-13. -8 and -5 multiply to 40 and add up to -13.
<span><span>(x−5)</span><span>(x−8)</span>=<span>x2</span>−13x+40</span>
You can use foil to test it
<span><span>x2</span>+<span>(−8x)</span>+<span>(−5x)</span>+40=<span>x2</span>−13x+40</span>
<span><span>x2</span>−13x+40=<span>x2</span>−13x+</span>
<span><span>−<span>13 x </span></span>≤ <span>− 6
</span></span>Step 1: Divide both sides by -13.
<span><span><span>−<span>13x/</span></span><span>−13 </span></span>≤ <span><span>−6/</span><span>−13</span></span></span><span>x ≥ <span>6/<span>13</span></span></span>
