Answer:
B. 8x² + 18x - 5
Step-by-step explanation:
(2x + 5)(4x - 1)
Use the distributive property to multiply 2x + 5 by 4x - 1.
8x² - 2x + 5(4x) + 5(-1)
8x² - 2x + 20x - 5
Combine 20x and -2x to get 18x.
8x² + 18x - 5
The expression for the area of the rectangle is 8x² + 18x - 5, which is B.

Answer:
Slope = [tex]- \frac{3}{4}[/tex]
Step-by-step explanation:
1. Choose 2 points from the graph
(0,-1) and (4,-4)
2.) Use this formula: [tex]\frac{y^{2}-y^{1} }{x^{2}-x^{1} }[/tex]
3.) (-4) - (-1) = -3

8 cubes are used to build a 2 by 2 Cube. How many cubes needed to build a cube that has three cubes along each edge?
Answer:
The number cubes needed when we have three cubes along each edge is 27 cubes
Step-by-step explanation:
The given parameters for the building of a cubic prism are;
The number of cubes used to build the 2 by 2 cube = 8 cubes
Let 'x' represent the length of each cube, we have;
The volume of a 2 by 2 cube = 2·x × 2·x × 2·x = 8·x³
Where x³ represents the volume of each cube
When we have three cubes along each edge, the total volume, becomes;
V = 3·x × 3·x × 3·x = 27·x³
The number cubes needed when we have three cubes along each edge, n = (The total volume of the cubes)/(The volume of each cube)
∴ The number cubes needed when we have three cubes along each edge, n = 27·x³/(x³/cube) = 27 cubes.

You are considering buying organic milk at the grocery store. A gallon of organic milk costs $1.00 more than a regular gallon of milk. Write an equation to represent the additional cost (C) of buying a gallon of organic mik over time (t) where x represents the cost of a gallon of regular milk
Answer:
C= $1t + x
Step-by-step explanation:
So, an organic gallon of milk is 1 dollar more then regular so the equation starts at $1 + x.
But then buying the organic milk over time is t so you add that to the one dollar since it applies to the organic milk. Now the equation is $1t + x.
But now, the expression we wrote is equal to C so, now the equation is C=$1t + x
Susie has a cylindrical candle mold with a height of 10 inches and a radius of 5 inches. Find the volume of the candle in terms of
7T
Which pair of angles are alternate exterior?????
Calculate the volume of the cylinder giving your answer to 1 decimal. Picture linked. Please I have a math test tomorrow I'll give extra points for explanation!!!
Answer:
549.5 cm³
Step-by-step explanation:
___________________________________________________________
FORMULA USED IN THE QUESTION :-
Volume of a cylinder whose height is 'h' and radius is 'r' = [tex]\pi \times r^2 \times h[/tex]
___________________________________________________________
According to the question ,
Height of cylinder (h) = 7 cm
Radius of cylinder (r) = 5 cm
Volume of cylinder = [tex]\pi \times 5^2 \times 7 = 3.14 \times 25 \times 7 = 549.5 \: cm^3[/tex]

An expression is shown below:
4(m + 3 + 5m)
Part A: Write two expressions that are equivalent to the given expression. (3 points)
Part B: Show that one of your expressions in Part A is equivalent to the given expression using algebraic properties. Explain which properties you used. (4 points)
Part C: Show that your other expression from Part A is equivalent to the given expression by substituting a number for m. (3 points)
Answer:
24m + 12 - - - (1)
12(2m + 1) - - - (2)
Step-by-step explanation:
Given the expression :
4(m + 3 + 5m)
Equivalent expressions include :
24m + 12 - - - (1)
12(2m + 1) - - - (2)
Using algebaraic properties :
4(m + 3 + 5m)
We can expand :
4m + 12 + 20m
4m + 20m + 12
24m + 12
Hence,
4(m + 3 + 5m) = 24m + 12
Using Substitution:
Let m = 5
4(m + 3 + 5m)
4(5 + 3 + 5(5))
4(5 +3 + 25)
4(33)
= 132
12(2m + 1)
12(2(5) + 1)
12(10 + 1)
12(11)
= 132
y = 2x - 4 y = x + 1
Solve using substitution.
