Answer:
It Is TrueIt is true because scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.
4x +40 = 80
Step by step how to solve?
Answer:
x=10
Let's solve your equation step-by-step:
4x+40=80
Step 1: Subtract 40 from both sides
4x+40−40=80−40
4x=40
Step 2: Divide both sides by 4
4x/4=40/4
Answer:
x=10
Answer:
collect like terms
4x=80 - 40
4x= 40
divide both sides by 4
4x/4÷ 40/4
x = 10

Graph the image of the figure using the transformation given.
(its multiple choice!)
The original image undergoes reflection across x=-3.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
In the given graph DEFG is the original image.
D'E'F'G' is the new image after the transformations applied.
A reflection is defined by the axis of symmetry or mirror line. In the above diagram, the mirror line is x = -3.
Under reflection, the shape and size of an image is exactly the same as the original figure.
This type of transformation is called isometric transformation.
Hence, the original image undergoes reflection across x=-3.

Han states that (b+6) has one factor. Explain why Han's thinking is correct.
1.The hidden factor of one does not count in the reporting.
2.The number 6 is the only number in the expression.
3.Anything in parentheses are considered factors.
4.If there is more than one term, then there is only one factor.
Answer:
2
Step-by-step explanation:
6 is not a factor only terms count as factors
The number 6 is the only number in the expression. Then the correct option is 2.
What is factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
Simply said, it is the biggest common element. The highest consistent element in the above example is 15, making 15 the greatest common factor amongst 15, 30, and 105. The biggest chunk of the common factors is called the "Greatest Common Factor" (of two or more numbers).
The expression is given below.
⇒ (b + 6)
The number 6 is a factor only terms count as factors because the variable b is the multiple of 6.
The number 6 is the only number in the expression. Then the correct option is 2.

Step-by-step explanation:
A project manager has ordered 252 pallets of concrete blocks for a construction project. Casone's trucks can each carry 14 pallets of blocks at a time. The project manager used partial quotients to find the number of delivery trucks to expect. His work is shown at the right. Is his solution correct? Explain
Answer:
18 trucks of delivery
Step-by-step explanation:
Total pallets of concrete blocks ordered = 252 pallets
If each truck can carry 14pallets, then;
1 truck = 14pallets
To determine the number of delivery truck 252pallets can carry, we can express this as:
x truck = 252pallets
Divide both expressions
1/x = 14/252
Cross multiply
14x = 1×252
14x = 252
x = 252/14
x = 18
Hence the manger should expect 1 18 trucks of delivery

A square has side length represented by X +4 inches write an expression to represent the area. Express your answer as a trinomial.
Answer:
[tex]A=(x^2+16+8x)\ \text{inches}^2[/tex]
Step-by-step explanation:
Given that,
The side length of a square, l = (x+4) inches
We need to find an expression to represent the area of the square.
The area of a square is given by :
[tex]A=\text{side}^2[/tex]
So,
[tex]A=(x+4)^2\\\\A=(x^2+16+8x)\ \text{inches}^2[/tex]
So, the area of the square is [tex](x^2+16+8x)\ \text{inches}^2[/tex].
