Answer:
Both the angles and sides are congruent.
Step-by-step explanation:
Regular polygons are considered to be equiangular and equilateral.
This means regular polygons have angles and sides that are all congruent.
if (ax+b)(ax+c)=4x^2-25 for all values of x, and a, b, and c are constants, what is the value of b+c?
Answer: 10.
Step-by-step explanation:
You are given the equation
(ax+b)(ax+c)=4x^2-25
Expand the Left hand side by opening the bracket.
a^2x^2 + axc + abx + bc
a^2x^2 + (axc + abx) + bc = 4x^2 + 0x - 25
From the equation above, we can see that;
a^2x^2 = 4x^2
a^2 = 4
a = √4
a = 2
Also, axc + abx = 0x
axc = abx
ax will cancel out from both sides
c = b
From the equation, bc = 25
But c = b. Substitute c for b
b^2 = 25
b = √25
b = 5 = c
b + c is therefore 5 + 5 = 10

Solve each system of equations by using elimination.
6a + 6b = 12
6a - 5b = 12
Select one:
a. (1,0)
O b.(2,0)
O c.(3,-0.5)
O d. (2,0.25)
Answer:
B. (2, 0)
Step-by-step explanation:
Step 1: Elimination (Subtract the 2 equations/add the 2 equations, one being negative)
b = 0
Step 2: Plug in b to get a
6a - 5(0) = 12
6a - 0 = 12
6a = 12
a = 2
What type of graph is this?
Answer:
Hello!
~~~~~~~~~~~~~~~~~
That would be parabola.
~~~~~~~~~~~~~~~~~
Step-by-step explanation: The graph of the quadratic polynomial is a parabola, with the horns pointing upwards if a > 0 or downwards if a < 0. Observe on the graph the behavior of the roots as you change the other two coefficients, b and c. Thus, it is a parabola.

If one quart of paint is exactly enough for two coats of paint on a 9-foot by 10-foot wall, how many quarts of paint are needed to apply one coat of paint to a 10-foot by 12-foot wall? Express your answer as a common fraction.
Answer:
2/3
Step-by-step explanation:
We are told in the question that
If one quart of paint is exactly enough for two coats of paint on a 9-foot by 10-foot wall
9 foot by 10 foot wall = an area of 9 × 10 = 90ft² × 2 coats of paint = 1 quart of paint
We are to find how many quarts of paint are needed
how many quarts of paint are needed to apply one coat of paint to a 10-foot by 12-foot wall .
10 × 12 = 120ft² × 1 coat of paint = x quart
Mathematically, if
One quart of paint = 90ft² × 2
x quart of paint = 120ft² × 1
Cross multiply
90ft²× 2 × x = 120ft²
x = 120/180
x = 2/3 quart of paint

A rectangle with an area of 192 square meters has a length and width in a ratio of 3:1. What are the length and width?
Hey there! :)
Answer:
Length = 24 meters.
Width = 8 meters.
Step-by-step explanation:
Recall that to find the area of a rectangle, the formula is as shown:
A = l × w
In this case, the length is 3 times the length of the width, or 3 : 1.
Let w = width, and
3w = length.
Find the value of w by plugging in these values into the equation:
192 = 3w · w
192 = 3w²
Divide both sides by 3:
64 = w²
Square root both sides:
w = 8 meters. This is the width.
The length is equivalent to 3w, so:
3(8) = 24 meters.

Which of the following can be represented by the equation below? $846 = $87 + $23M A. Tom wants to save $87, he already has $23, and he deposits $846 each month, M. B. Tom wants to save $846, he already has $87, and he deposits $23 each month, M. C. Tom wants to save $87, he already has $846, and he deposits $23 each month, M. D. Tom wants to save $846, he already has $23, and he deposits $87 each month, M.
Answer:
The answer is C.
Answer:
B. Tom wants to save $846, he already has $87, and he deposits $23 each month, M.
Step-by-step explanation:
$846 = $87 + $23M
The $846 represents the amount that he wants to save. $23M represents how much money he wants to deposit every M months. $87 represents the amount that he has already deposited (the constant).
And so, the correct answer will be B. Tom wants to save $846, he already has $87, and he deposits $23 each month, M.

What is the intersection of the lines x = -15
and y=5 ?
Answer:
the point on the plane (-15, 5)
Step-by-step explanation:
These lines are:
1) a vertical line (x=-15) which implies that all x values of the points that it contains have coordinate x= -15
2) a horizontal line (y=5) which implies that all y values of the points that it contains have coordinate y = 5
Then the intersection must occur at x = -15 and y = 5, that is at the point (-15, 5)
80.5 square feet scaled up by a factor of 10
Answer:
805
Step-by-step explanation:
Scaling up by a factor of ten means that you must multiply the original number by 10. Because 10 has one zero, the best way to figure this out is just moving the decimal to the right ONCE (just like there is ONE zero)! This gives us 805.

Which of the following equations has a solution of x = -5?
a. Equation A
b. Equation B
c. Both A and B
d. Neither A nor B
Answer:
C. Both A & B
Step-by-step explanation:
Solve the equations given:
Equation A:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 11x and add 7 to both sides:
16x (-11x) - 7 (+7) = 11x (-11x) - 32 (+7)
16x - 11x = -32 + 7
Simplify. Combine like terms:
16x - 11x = -32 + 7
5x = -25
Isolate the variable, x. Divide 5 from both sides:
(5x)/5 = (-25)/5
x = -25/5
x = -5
Equation A is an answer choice.
Equation B:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 10 & subtract 2x from both sides:
-4x (-2x) - 10 (+10) = 2x (-2x) + 20 (+10)
-4x - 2x = 20 + 10
Simplify. Combine like terms:
-4x - 2x = 20 + 10
-6x = 30
Isolate the variable, x. Divide -6 from both sides:
(-6x)/-6 = (30)/-6
x = 30/-6
x = -5
Equation B is also an answer choice.
C. Both A & B is your answer.

what is the probability of rolling a 3 on two consecutive rolls of a fair 6-sided die?
Answer:
[tex]\frac{1}{36}[/tex] chance
Step-by-step explanation:
Each time you roll a die, you have a [tex]\frac{1}{6}[/tex] chance of rolling a 3. It's even rarer to roll two 3s in a row, and to find a consecutive probability, we have to multiply the two probabilities. In this case, both probabilities are [tex]\frac{1}{6}[/tex].
[tex]\frac{1}{6}\cdot\frac{1}{6}=\frac{1}{36}[/tex]

In general for a rectangle of dimensions w by h and a semicircle of diameter w we get an area:
A = wh + \frac 1 2 \pi (\frac w 2)^2
The halfs are because a semicircle is half a circle and a radius is half a diameter.
We're told
h = 1+ 3w
Substituting,
A(w) = w(1+3w) + \frac 1 2 \pi (\frac w 2)^2

Answer:
x= 3/2 = 1.5
Step-by-step explanation:
● 5(4x-10)+10x =4(2x-3)+2(x-4)
Simplify the products
● 5*4x-5*10+10x = 4*2x-4*3+2*x-2*4
● 20x-50+10x = 8x-12+2x-8
Add the terms that don't contain x with each other
●20x-50+10x = 8x-20+2x
Add 20 in both sides
●20x-50+20+10x = 8x-20+2x+20
●20x-30+10x = 8x+2x
Add together the terms that contain x
●30x -30 = 10x
Add -10x in both sides
●30x-30-10x = 10x-10x
● 20x -30 = 0
Add 30 in both sides
● 20x-30+30 = 30
● 20x = 30
Divide both sides by 20
●20x/20 = 30/20
● x= 30/20
● x= 3/2
● x= 1.5
