Answer:
<u>f</u><u>(</u><u>5</u><u>)</u><u> </u><u>=</u><u> </u><u>1</u><u>7</u><u> </u>
Step-by-step explanation:
f(x) = 3x + 2
Since the value of x is 5, we can plug it into the equation.
f(5) = 3(5) + 2
f(5) = 15 + 2

What r the numbers I can't help you out if I don't have the numbers
Ok
Part B: Both of the children are incorrect. The children have the same amount of money
Explanation: they have the same amount because 6 dimes are 60 cents... Hannah says she has 60 cents while Mason says he has 6 dimes. Got it?
Part A: 6 dimes = 60 cents
Explanation: None
Answer:
First, we know that the area of a rectangle of width W and length L is:
A = W*L
In the case of Roberto's plan, we can see that the length of the whole rectangle is:
L = 1.5ft + x + 1.5ft = 3 ft + x
And the width is:
W = 3ft + x + 3ft = 6ft + x
Then the area of the whole thing is:
A = (3ft + x)*(6ft + x)
This is what we wanted, a product of two polynomials that represents the area of Roberto's plot.
Now if we subtract the white square (is a square of sidelength x, then its area is A = x*x) we will get the area of the border;
The total area of Roberto's borders is:
Area of the border = (3ft + x)*(6ft + x) - x*x
= 3ft*6ft + 3ft*x + x*6ft + x^2 - x^2
= x*9ft + 18ft^2
You can make an equation with these numbers.
182 ÷ 2 = 91 ÷ 2 = 45.5
Hope this helps!
