(4v-4)° (5v-5)°
Answer:
20v2−40v+20
Step-by-step explanation:
=(4v+−4)(5v+−5)
=(4v)(5v)+(4v)(−5)+(−4)(5v)+(−4)(−5)
=20v^2−20v−20v+20
= 20v^2-40v+20
You can easily do this by using the FOIL method.
F - first - in this case, 4v and 5v
O - Outside - in this case, 4v and -5
I - Inside - in this case, -4 and 5v
L - Last - In this case, -4 and -5
Then you find the like terms and add them together and then you have your answer which is also in standard form.
Please and thank you

6. Solve: 143 = 13y
Answer:
y=11
Step-by-step explanation:
To isolate the variable, y, you need to divide by 13 on both sides. 13y/13 cancels out, so you are left with 143/13. 143 ÷ 13 is 11, so y = 11.
To Check your answer:
Substitute y for 11. Your equation will be 143 = 13 x 11. Does 13 x 11 = 143? Yes.
Answer:
y=11
Step-by-step explanation:
you have to divide both sides of the equation by the same term and then simplify

A special box designed to hold an antique artifact is shaped like a triangular prism. The surface area is 439.2. The height of the base triangle is 6.9 and each side is 8. What is the height of the box?
Answer:
h = 16 unit
Step-by-step explanation:
The formular for the surface area of a triangular prism is given as,
A = ab+3bh............................ Equation 1
Where A = surface area of the triangular prism, a = height of the base triangle, b = base of the triangle, h = height of the box.
make h the subject of the equation
h = (A-ab)/3b........................ Equation 2
Given: A = 439.2, a = 6.9, b = 8
Substitute into equation 2
h = [439.2-(6.9*8)]/(3*8)
h = (439.2-55.2)/24
h = 16.
Hence the height of the box is 16 unit

1/4 chance of choosing an 'm'
1/2 chance of getting tails
Probability of both events = 1/4 * 1/2 = 1/8
If f(x) = x 2 + 1 and g(x) = 3x + 1, find 2·f(4).
Step-by-step explanation:
Given
f(x) = x² + 1 and g(x) = 3x + 1
Now
2 • f(4) = 2 ( 4² + 1)
= 2 * 17
= 34

What is a Function?A function is a law that relates two variables namely, a dependent and an independent variable.
A function always has a defined range and domain, domain is all the value a function can have as input and range is all the value that a function can have.
The function is of various types, logarithmic, exponential, quadratic, radical, etc.
The function is shown in the image,
The function is a hyperbolic function, represented by x²/a² -y²/b² = 1 for a hyperbola having a center at the origin.
The function can give any value from the set of real numbers and so,
The range of the function is a set of real numbers.

How do i find the slope
Answer:
the slope is x 0 y-9
Step-by-step explanation:
very very very sorry if it's wrong I apologize
Answer:
Slope = -3/1
Step-by-step explanation:
As the hint says, slope is the change in y over the change in x or
m = (y2 - y1)/(x2 - x1)
m = (9 - 15)/(2 - 0)
m = -6/2
m = -3/1
