Answer:
Step-by-step explanation:
Given:
Given equation is.
Find values of x?
Solution.
Find the roots of the equation.
compare the above equation with
Therefore,
Put a,b and c value in above equation.
For positive sign
For negative sign
Therefore, the value of satisfy the given equation.
9 x 3.5 = 31.5
2 x 2 = 4
2 x 2 = 4 / 2 = 2
2 x 5 = 10/ 2 = 5
31.5 + 4 + 2 + 5 = 42.5^2
Answer: 20 lawns could be mowed in 35 hours.
Step-by-step explanation: Lets write a ratio to represent this problem. The ratio 7:4 states that for every 7 hours you will mow 4 lawns.
Now we have to figure out how many lawns we will mow in 35 hours. Simply keep adding 7 to the left side of the ratio and 4 to the right side.
7:4
14:8
21:12
28:16
35:20
So in 35 hours, 20 lawns will be mowed.
Slope: (y2-y1)/(x2-x1)
Plug in the numbers
3/2 = (9-r)/(-4-6)
9 - r = -15, r = 24
Answer: r = 24
If the 3’s were exponents then... i got 50r3
how i solved:
39r3 + 11r3 + 45s3 - 5s3 - 40s3
50r3 + 40s3 - 40s3
50r3 + 0
= 50r3
