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 is 125

Answer:
x = 24.1
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp /adj
tan 15 = x/90
90 tan 15 =x
x=24.11542
To the nearest tenth
x = 24.1
