Answer:
A.
Step-by-step explanation:
The sum of a number, x, and 4 just means x + 4.
If we take twice this sum, it implies that we take the resulting number and multiply it by 2.
Our resulting number is x + 4, so we are left with 2(x + 4).
I hope this helps!
The correct answer is twice the sum of a number and four.
What is an expression?Expressions in maths are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given an expression, 2(x+4)
The sum of a number, x, and 4 just means x + 4.
Taking twice of the sum, it implies that we take the resulting number and multiply it by 2.
The resulting number is x + 4, so it is 2(x + 4).
Hence, The correct answer is twice the sum of a number and four.

Can someone help me simplify these expressions
Step-by-step explanation:
4. Let's multiply the coefficients. 2 * 6 * (-5) = -60. As for the exponents, since they have the same base we'll just add the exponents giving us s^(2 + 1 + 4) = s^7 so the answer is -60s^7.
7. -2/3 * -1/2 * -4 = -4/3 and the exponent is b^(2 + 3 + 4) = b^9 so the answer is -4/3b^9

to make the perfect shade of orange cake frosting, Mya needs 8 drops of yellow food coloring for every 12 drops of red food coloring. If she adds 32 drops of yellow food coloring to her frosting, how many drops of red food coloring should she add?
Answer:
First find how much more the recipe increased by
32/8=4
She needs to have 4 times more the recipe
Since she multiplied the 8 drops of yellow by 4 we need to balance the food coloring and multiply the red food coloring by 4
12 x 4 = 48 drops of red food coloring
48 drops

Step-by-step explanation:
you are emailing your cousin a care package in a box shaped like a cube. Each side of the box is 6 inches long. You mist cover the box with brown wrapping paper in order for the post office to accept it. What is the minimum amount of brown wrapping paper you will need in order to completely cover the box
==========================================================
Work Shown:
x = side length of cube = 6 inches
SA = surface area of cube
SA = 6x^2
SA = 6*6^2
SA = 6*36
SA = 216 square inches
------------
side note: if you have a rectangular box that isn't a cube (ie the length, width, and/or height aren't all the same), then you would use this formula to get the surface area
SA = 2*(L*W+L*H+W*H)
where L,W,H are the length, width and height respectively.

Answer:
A intersection B or A Π B
Step-by-step explanation:
The intersection of A and B is the set of all those elements which belong to both A and B.
In given Venn diagram describe the shading region is A intersection B or A ∩ B
What is Venn diagram?A Venn diagram is an illustration that uses circles to show the commonalities and differences between things or groups of things Venn diagrams, also called Set diagrams or Logic diagrams, are widely used in mathematics, statistics, logic, teaching, linguistics, computer science and business. Many people first encounter them in school as they study math or logic, since Venn diagrams became part of “new math” curricula in the 1960s. These may be simple diagrams involving two or three sets of a few elements, or they may become quite sophisticated, including 3D presentations, as they progress to six or seven sets and beyond. They are used to think through and depict how items relate to each within a particular “universe” or segment. Venn diagrams allow users to visualize data in clear, powerful ways, and therefore are commonly used in presentations and reports. They are closely related to Euler diagrams, which differ by omitting sets if no items exist in them. Venn diagrams show relationships even if a set is empty.
According to the question
The intersection of A and B is the set of all those elements which belong to both A and B.
Hence, the given Venn diagram describe the shading region is A intersection B or A ∩ B

Olive's Pizza Kitchen has a new oven that is shaped like a rectangular prism. Inside, the oven is 5 feet wide and 5 feet deep so it can bake their super large pizzas. It is also 3 feet high. What is the oven's volume?
Answer:
The volume of the oven is 75 ft^3
Step-by-step explanation:
Here, we are interested in calculating the volume of a Pizza Kitchen’s oven which is shaped like a rectangular prism.
Now, to calculate this volume, what we do is to simply multiply the area of the base by the height of the oven.
Mathematically, the area of the base of the oven is simply = L * B = 5 * 5 = 25 ft^2
Now to get the volume, we multiply this by the height = 25 * 3 = 75 ft^3

a factor of 30 is chosen at random, what is the probability that the number has 2 digits?
Answer:
3/8
Step-by-step explanation:
Let's first start by figuring out all the factors of 30.
They are as follows: 1, 2, 3, 5, 6, 10, 15, 30
30 has 8 factors in total.
3 of the factors have 2 digits.
Probability is number of desired outcomes/number of total outcomes.
We have 3 desired outcomes and 8 total outcomes.
Therefore, the probability that the factor chosen at random will have 2 digits is 3/8.

Answer:
x = 33
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
x+114+33 = 180
Combine like terms
x+147 = 180
Subtract 147 from each side
x+147-157 = 180-147
x = 33
Answer:
x=33
Step-by-step explanation:
The interior angles of a triangle must add up to 180 degrees. Therefore, the 3 angles inside the triangle should add to 180.
x+114+33=180
Combine like terms by adding 114 and 33
x+147=180
In order to solve this equation, we must get x isolated. Perform the inverse operation to both sides.
x+147=180
147 is being added on to x. The inverse of addition is subtraction. Subtract 147 from both sides.
x+147-147=180-147
X=180-147
x=33
x is equal to 33 degrees.
