We have,
Graph.
We see that,
The polynomial on the graph has two intercepts.
x-intercept at x = -3 and y-intercept at -1.
This means that,
The roots of the polynomial can be
f(x) = (x + 3)
The degree of the polynomial is the highest power in the terms given in the polynomial with a non-zero coefficient.

dm the answer bc its glitched heres the question Gabi tried to solve an equation step by step.
0.1(0.5m+6)=2
Answer:
m = 28
Step-by-step explanation:
The given expression is :
0.1(0.5m+6)=2
Step 1.
Use distributive property:
0.1(0.5m) +0.1(6) = 2
0.05 m+ 0.6 = 2
Step 2.
Subtract 0.6 both sides
0.05 m+ 0.6 -0.6= 2 -0.6
0.05 m = 1.4
or
0.5 m = 14
Step 3.
Divide both sides by 0.5
[tex]m=\dfrac{14}{0.5}\\\\m= 28[/tex]
Gabi's third step is not correct. It should be m = 28 instead of m = 7.
The total surface area of this cuboid is 112cm^2. Find the value of x.
Please explain, don’t just give the answer.
Answer:
The value of x is 3
Step-by-step explanation:
Let us study the face of the cuboind
∵ The cuboid has 6 rectangular faces
∵ Each opposite faces area equal in areas
∴ 2 faces of dimensions 10 cm and 2 cm
∴ 2 faces of dimensions 10 cm and x cm
∴ 2 faces of dimensions 2 cm and x cm
∵ The total surface area of the cuboid is the sum of the areas of the 6 faces
∵ The area of the rectangle = length × width
∴ The total surface area = 2(10 × 2) + 2(10 × x) + 2(2 × x)
∴ The total surface area = 2(20) + 2(10x) + 2(2x)
∴ The total surface area = 40 + 20x + 4x
→ Add the like terms 20x and 4x
∴ The total surface area = 40 + 24x
∵ The total surface area of this cuboid is 112 cm²
→ Equate the two sides of the total surface area
∴ 40 + 24x = 112
→ Subtract 40 from both sides
∵ 40 - 40 + 24x = 112 - 40
∴ 24x = 72
→ Divide both sides by 24
∴ x = 3
∴ The value of x is 3
Answer:
= 3
Step-by-step explanation:

x = L, 10 = B, 2 = W
L x B
x 10 = A1
L x W
x 2 = A2
B x W
10 x 2 = 20 (A3)
= 112cm^2 / 2 = 56cm - 20 = 36
3 x 10 = 30
3 x 2 = 6
30 + 6 = 36
36 + 20 = 56cm
56cm x 2 = 112cm^2

The cylindrical part of a architectural column has a height of 325 cm and a diameter of 30 cm. Find the volume of the cylindrical part of the column. Use 3.14 for π and round your answer to the nearest cubic centimeter if needed.
Answer:
[tex]V=229612.5\ cm^3[/tex]
Step-by-step explanation:
Given that,
The height of a cylinder, h = 325 cm
Diameter, d = 30 cm
Radius, r = 15 cm
We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :
[tex]V=\pi r^2h[/tex]
Putting all the values,
[tex]V=3.14\times (15)^2\times 325\\\\V=229612.5\ cm^3[/tex]
So, the volume of the cylinder is [tex]229612.5\ cm^3[/tex].

A beekeeper pours honey into jars. Each large jar holds 18 ounces of honey. Each small jar holds 12 ounces of honey. The beekeeper fills 32 large jars and 46 small jars.
Which answer is the most reasonable estimate of the total amount of honey in the jars?
800 ounces because 10 × 30 + 10 × 50 = 800
1,000 ounces because 20 × 30 + 10 × 40 = 1,000
1,100 ounces because 20 × 30 + 10 × 50 = 1,100
1,600 ounces because 20 × 30 + 20 × 50 = 1,600
Answer:
1,100 ounces because 20 × 30 + 10 × 50 = 1,100

A stack of books is 5 feet 5 inches high. How high is it in inches?
Well first, you have to know that there are 12 inches in a foot so, that's 12 / 3 = 4, so that means that for every foot, there are 4 books. The books are 5 feet tall so 4 x 5 = 20. Your answer is: 20 books are in a stack.
Answer:
Step-by-step explanation: I would do 5x12 because there are 12 inches in one foot so 5x12 is 60 so there is 60 inches

Which model represents 2.36 ÷ 4? A. Three groups of three tenths and four hundredths B. Three groups of five tenths and nine hundredths C. Four groups of three tenths and six hundredths D. Five groups of five tenths and nine hundredths
Answer:
Five groups of five tenths and nine hundredths
Step-by-step explanation:
Mathematically;
2.36 divided by 4 = 0.59
So we want to select from the options, the best representation of this
That will be
0.5 + 0.09
so our answer is 5 groups of five tents and nine hundredths
The model which represents 2.36 ÷ 4 is; Choice D: Five groups of five tenths and nine hundredths
We must perform the division 2.36 ÷ 4 first so that we have;
2.36 ÷ 4 = 0.59The result, 0.59 can then be written in words as; Five tenths and 9 Hundredths.
Ultimately, the model. which represents the expression 2.36 ÷ 4 is; Choice D: Five groups of five tenths and nine hundredths.

Answer:
D. (-3, -2)
Step-by-step explanation:
The equations have different coefficients for x and y, so will have one solution. The solutions offered are easily tested in either equation.
Using (x, y) = (-2, -3):
x = y -1 ⇒ -2 = -3 -1 . . . . False
Using (x, y) = (-3, -2):
x = y -1 ⇒ -3 = -2 -1 . . . .True
2x = 3y ⇒ 2(-3) = 3(-2) . . . . True
The solution is (-3, -2).
__
If you'd like to solve the set of equations, substitution for x works nicely.
2(y -1) = 3y
2y -2 = 3y . . eliminate parentheses
-2 = y . . . . . . subtract 2y
x = -2 -1 = -3
The solution is (x, y) = (-3, -2).
