Answer:
5
Step-by-step explanation:
Well, if he mowed 13 total and 8 of them on Saturday you would solve like this:
13 - 8 = ?
13 (Total amount He Did)
8 (Amount he did on Saturday)
? (Amount he did on Sunday)
Which,
13 - 8 = 5
Meaning, he mowed 5 lawns on Sunday!

The exponential function f(x) can represent growth or decay
The value of f(14) is 226.07
<h3>How to determine the value of f(14)?</h3>
The given parameters are:
f(-2) = 25 and f(7) = 85
An exponential function is represented as:
f(x) = ab^x
So, we have:
ab^-2 = 25
Also, we have:
ab^7 = 85
Divide both equations.
This gives
b^9 = 3.4
Take the 9th root of both sides
b = 1.15
Recall that:
ab^7 = 85
This gives
a* 1.15^7 = 85
Solve for a
a = 31.95
So, the exponential function is:
f(x) = 31.95 * 1.15^x
Substitute 14 for x
f(14) = 31.95 * 1.15^14
f(14) = 226.07
Hence, the value of f(14) is 226.07

Answer:
x = 4
Step-by-step explanation:
The figure is a rhombus when the sides are the same length.
21 -x = 2x +9
12 = 3x . . . . . . . . add x-9 to both sides
4 = x . . . . . . . . . . divide by 3

Answer:
B. x(x) + (−6)(−3)
NOT equivalent to (x − 6)(x − 3)
Step-by-step explanation:
(x − 6)(x − 3)
= x^2 - 3x - 6x + 18
= x^2 - 9x + 18
A. (6 − x)(3 − x)
= 18 - 6x - 3x + x^2
= 18 - 9x + x^2
= x^2 - 9x + 18 ---->equivalent to (x − 6)(x − 3)
B. x(x) + (−6)(−3) = x^2 + 18 ----> NOT equivalent to (x − 6)(x − 3)
C. x2 − 3x − 6x + 18 = x^2 - 9x + 18 --> equivalent to (x − 6)(x − 3)
D. x(x − 6) − 3(x − 6)
= x^2 - 6x - 3x + 18
= x^2 - 9x + 18 ---->equivalent to (x − 6)(x − 3)
