No...you can think of it like 900 and 90 which will give you about 10 so 100 is way off
Use the FOIL (first, outside, inside, last) to expand the terms in the brackets.
(w - 7)(w + 4)
first: w × w = w²
outside: w × 4 = 4w
inside: -7 × w = -7w
last: -7 × 4 = -28
Now you add all the terms together to get:
w² + 4w - 7w - 28
This simplifies to give you:
w² - 3w - 28
Hope that helps! :)
AA3 + 2 = AAA;
<span><span>3 + 2 = 5; </span><span>- >> A = 5; </span><span>AAA = 555. </span></span>
<span>
CC6 + 6 = CBB; </span>
<span><span>6 + 6 = 12; </span><span>- >> B = 2; </span><span>one goes to the left and C (1 +?) turns into B; </span><span>and B already found = 2; </span></span>
<span><span>C = B-1 = 2-1 = 1; </span><span>- >>> C = 1; </span><span>SVB = 122; </span></span>

Let's say each side is 5 and 5 so all you have to do is times 5 bye 5 and divide the two numbers by 20 and when you get that then you add the numbers by 180 then your answer is 239cm
