Step-by-step explanation:
(x−1)²−9=0
(x-1)²= 9
x-1 = ±√9
x-1 = ±3
x = 1-3=-2 or x=1+3=4
the solution = {-2,4}
Answer:
Step-by-step explanation:
On the first day, Ben (B) starts with 10 tubs and Winston (W) starts with 0 tubs.
After the first day, Ben sells 8 tubs per day while Winston sells 9 tubs per day.
Therefore we can write the following equation: (Where d = number of days)
B = 10 + 8d
W = 0 + 9d = 9d
We are told that eventually they will sell the same amount which means
B = W
This means we can say,
10 + 8d = 9d
If we subtract 8d from both sides we get
10 = d
Therefore it will take 10 days for them to sell the same amount of cookie dough.
Answer:
or around 57.88
Step-by-step explanation:
We can find the base length by using the formula for the area of a triangle.
Plug in the values that we know, the area and the height, and solve for 
.
![b=\frac{984}{17}So the base is [tex]\frac{984}{17}](https://tex.z-dn.net/?f=b%3D%5Cfrac%7B984%7D%7B17%7D%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3ESo%20the%20base%20is%20%5Btex%5D%5Cfrac%7B984%7D%7B17%7D)
or about 57.88 if you round to the nearest hundredth.

Use seconds as the standard unit to compare the speeds of the 4 runners
Tony is already in standard form and runs 12 ft/s
Katie:
450/30
15 ft/s
Frank:
1 mile = 5280 feet
5280/577
9.15 ft/s
Adam:
I minute = 60 seconds
