Answer:
1. (n + 3)(5n + 8)
2. (x - 4)(7x - 4)
3. (k + 8)(7k + 1)
Step-by-step explanation:
1. We have to factorize 5n² + 23n + 24.
Now, 5n² + 23n + 24
= 5n² + 15n + 8n + 24
= 5n (n + 3) + 8 (n + 3)
=(n + 3)(5n + 8) (Answer)
2. We have to factorize 7x² - 32x + 16
Now, 7x² - 32x + 16
= 7x² - 28x - 4x + 16
= 7x (x - 4) - 4 (x - 4)
= (x - 4)(7x - 4) (Answer)
3. We have to factorize 7k² + 57k + 8
Now, 7k² + 57k + 8
= 7k² + 56k + k + 8
= 7k (k + 8) + 1 (k + 8)
= (k + 8)(7k + 1) (Answer)
Answer:
FIND THE HOLE SIZE IN THIS CASE THERE IS NO SIZE SO ZERO IS THE AWNSER
pls can i have brainliest
Answer:
17
Step-by-step explanation:
f(x) = 3x + 2
f(5) = 3(5) + 2 = 17
Answer:
The pressure at 4000 m is about 59 kilopascals
Step-by-step explanation:
The equation is of the form
y= a b^x
where a is the initial value, b is 1 - percent decrease, and x is the number of 1000 m increases
a = 96 kilopascals
b = 1- 11.4%
=1-.114
= .886
y = 96 (.886)^x
We go up 4000 m so x = 4000/1000 = 4
y = 96(.886) ^4
y = 59.156997121536
The pressure at 4000 m is about 59 kilopascals
