Answer:
Option (b) is correct.

Step-by-step explanation:
Given expression "four times the square of a number is thirty-six"
We have to write it mathematically and choose the correct options out of given options.
Consider the given expression "four times the square of a number is thirty-six"
Then
let the number be x ,
Then four times the square of a number written mathematically as 
And given "four times the square of a number is thirty-six" written mathematically as 
Therefore, "four times the square of a number is thirty-six" written mathematically as 
Option (b) is correct.
Answer:
$2492.10
Step-by-step explanation:
- Deposit amount = $2130
- Interest rate = 4.25% annual simple
- Time = 4 years
<u>Balance at the end of 4 years:</u>
- $2130*(1 + 4*0.0425) = $2492.10
3.007 ounces per square meter
Find the gradient
m = y2-y1 / x2-x1
m = 4-(-2) / 3-(-3)
m = 6 / 6
m = 1
Insert the values of one of the points into y=mx+c to find c (choosing point (3,4)):
y = mx + c
4 = 1(3) + c
c = 4 - 3
c = 1
Therefore, the equation is:
y = x + 1
Um, I think it's:
(x) + (x+6) = 42
