20x^4-39x^3-16x
Make sure to multiply all the terms by each other in the two parentheses
Answer:
x = -11
Step-by-step explanation:
I'm assuming it's an isosceles triangle so 32 + 2x = 10;
subtract 32 from both sides;
2x = -22
x = -11
Answer:
$672
Step-by-step explanation:
First find the area so:
5*4=20ft
2^2*3.14=12.56ft
20+12.56=32.56ft
Second find the price for the area:
32.56*12=$672
Hopefully it's correct!
1:3 is the ratio to boys and girls. I know that 1/4 must be girls. 3/4 will be boys.
Divide 236 by 4.
236/4= 59
Multiply that by 3.
59*3= 177
177 of the students are boys.
I hope this helps!
