Answer : He saved $30 money.
Step-by-step explanation :
when he earned $15 from babysitting, he saved money = 6 dollars
when he earned $1 from babysitting, he saved money = dollars
when he earned $75 from babysitting, he saved money = dollars
Therefore,He saved $30 money.
There are 5 fifteens in 75
There are 6 dollars saved everytime he makes 15 dollars
6 x 5 = 30
He saved 30 dollars

Final answer:
The expression to represent the area of the shaded region is (5x + 2)(x + 7) - (3x - 1)(x + 7). Simplifying the expression gives us 2x^2 + 42x + 7.
Explanation:
To find the area of the shaded region, we need to subtract the area of the smaller rectangle from the area of the larger rectangle. The larger rectangle has a length of (5x + 2) and a width of (x + 7), while the smaller rectangle has a length of (3x - 1) and a width of (x + 7). Therefore, the expression to represent the area of the shaded region is:
(5x + 2)(x + 7) - (3x - 1)(x + 7)
To simplify this expression, we can use the distributive property. First, we simplify the expression in the parentheses:
(5x + 2)(x + 7) - (3x - 1)(x + 7)
(5x^2 + 35x + 2x + 14) - (3x^2 - 7x - x + 7)
Next, we distribute the negative sign:
5x^2 + 35x + 2x + 14 - 3x^2 + 7x + x - 7
Finally, we combine like terms:
2x^2 + 42x + 7

Answer:
Step-by-step explanation:
To determine what the area of the shaded region is, simply find the area of the large rectangle and subtract the product from the smaller one.
Since they are polynomials. Multiply one binomial to the other and first obtain the product, before subtracting the product of the smaller rectangle.
(5x + 2)(3x - 1) - (x)(x + 7)
15x^2 - 5x + 6x - 2 - x^2 - 7
14x^2 + x - 9.
I believe this would be the solution in standard form.

xyz=(x)(y)(z)
if x and y and z are all perfect cubes, xyz is also a perfect cube
remmeber
(x^n)^m=x^(mn)
so if it is perfect cube it can be factored into
(x^n)^3, such taht n is a whole number
basiclaly, see if the expoent is divisble by 3
all of them should be perfect cubes
215x^18y^3z^21
split them up to see which ones need changing
215=5*43, not a perfect cube
could be changed to 6^3, which is 216
x^18=(x^6)^3
y^3=y^3
z^21=(z^7)^3
the 215 needs to be changed

The amount of time his teammate have to catch the ball is equal to 1.774 seconds.
Given the following function:
- f(x) = -16t² + vt + s.
- Displacement, s = 6ft.
- Velocity, v = 25 ft/s.
How to calculate the amount of time?
In order to determine the amount of time his teammate have to catch the ball, we would evaluate the given position-time function as follows:
f(t) = -16t² + 25t + 6.
In Mathematics, the standard form of a quadratic equation is given by;
ax² + bx + c =0
Where:
a = -16.
b = 25.
c = 6.
Solving the function by using the quadratic formula, we have:
t = [-b ± √(b² - 4ac)]/2a
t = [-25 ± √[(25² - 4(-16)(6))]/2(-16)
t = [25/32 ± (-1/32)√1009]
t = 25/32 ± (-0.993)
t = 0.781 ± 0.993
t = 0.781 + 0.993
Time, t = 1.774 seconds.
Note: We ignored the negative value because time cannot be negative.

So, in your question you know that 4 times a number equals 5616.
To find this number, we can just divide 5616 by 4.
5616 / 4 = 1404
Therefore, 4 times 1404 equals 5616.
Hope this helps! :)

What is the linear system?
A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
The linear function is given below.
y = -2x + 3
Then the graph of the equation will be
Put x = 0, then the value of y will be
y = -2(0) + 3
y = 3
Put y = 0, then the value of x will be
2x = 3
x = 1.5
Then the coordinates will be (0, 3) and (1.5, 0).
Mark these points on the paper and make a straight line.
The graph is given below.
