Roots of the polynomial are values of x when f(x)=0,so
to find the roots of the polynomial we need to solve the equation
x²+9x-70=0 , a=1, b=9,c=-70
The answer is 1/140

I did this with cross multiplication.
The fraction on the right is 35% over 100%. the 35% represents the percentage the 6th graders raised of the total money raised.
The fraction on the left is x (representing how many dollars the 6th graders raised, what we're trying to find) over $240, the total amount raised by the school.
1. cross multiply 35 with 240.
35x240=8400
2. Since we are looking for x and 100 is across from it you divide what you got from the first multiplication by 100
8400/100=(100*x)/100
=$84
169 since it is a square so all sides are equal and 52 divided by 4 is 13 then 13 times 13 is 169.
Answer:
351
Step-by-step explanation:
The top box draw a line and then it will be just 9*9
then you have 30ft * 9ft
30*9 = 270
9*9 = 81
270+81 = 351
