Answer:
(x-3) (x+5) => x*x+5x-3x-15
=> x*x+2x-15
Step-by-step explanation:
Circumference = 2 · π · r or π · d
Radius = 7.8
7.8 × 2 = 15.6
15.6 × 3.14(π) = 48.984
Circumference = 48.984 rounded = 49
Area = π · r²
Radius = 7.8
7.8 × 7.8 = 60.84
60.84 × 3.14(π) = 191.0376
Area = 191.0376 rounded = 191
Hope this helped☺☺
Yes what’s the question ?
Not sure if this is for algebra but this is the algebraic solution.
1. 5x + 1y = 25 (x meaning number of nickels) (y meaning number of pennies)
so 3 solutions could be, 5 nickels and 0 pennies, 4 nickels and 5 pennies, 3 nickels and 10 pennies.
2. First calculate how many days till the end of October, (31-14)= 17 days. then add 30 days for the entire month of November. Then add the 5 days that occurred in December. This will leave you with a total of 52 days.
This function is sketched on the A picture.
<span>y – 2 = 2/3(x – 6)
</span>y = 2/3x - 4 + 2
y = 2/3x - 2
y = ax+b
b = -2
b is y-intercept
Zero of the function:
0 = 2/3x - 2
2 = 2/3x
x = 3
y-intercept (0, -2)
x- intercept (3, 0)
