Answer:
25x^2+40x+16
Step-by-step explanation:
We have to distribute each term to the other terms.
Let's take the first 5x and multiply it by 5x and 4 in the second set of parentheses.
5x*5x+5x*4
25x^2+20x
Now we have to multiply the first 4 by, again, 5x and 4
4*5x+4*4
20x+16
Now we combine the two bolded expressions.
25x^2+20x+20x+16
Now we combine like terms
25x^2+40x+16
Hope this helps!
Answer:
x = 54°
y = 66°
Step-by-step explanation:
x + y = 120° (given)
x = y - 12
Then, y + y - 12 = 120°
(y + y) - 12 = 120°
2y - 12 = 120°
2y = 120 + 12 = 132°
y = 132/2 = 66°
x = y - 12 = 66 - 12 = 54°
There you go :)
48 lol I think
120 x 80%
80% because 4/5 of his text are to friends
96/ one half
One half because half of his text are to her
