A. close to 3.2. B. close to 0.32 C. close to 320 or D. close to 32?
Answer:
8.1x^4 x 0.2 = 1.62x^4
Step-by-step explanation:
The estimated multiplication of 8.1 and 4.2 is close to 32.
What is a decimal?A decimal is represented by a dot that separates the whole part and the fractional part of a number. Decimals can also be converted into fractions and vice versa.
Estimations are essential when we don't have a tool to calculate the exact value of something.
Given A multiplication of two decimal numbers 8.1 and 4.2.
Now 8.1 can be estimated as 8 and 4.2 can be estimated as 4 and we know 8 times 4 is 32 so, the multiplication of 8.1 and 4.2 is close to 32.

What is the measure of angle ECD?
a 79
b 90
c 9
d 17
Answer:
(A) 79º
Step-by-step explanation:
We can set up a simple equation to solve this, by using supplementary angles and the information that the problem has given:
x - 8 + 90 + 4x + 3 = 180
Now, we can solve:
x - 8 + 4x + 3 = 90
x - 5 + 4x = 90
5x = 95
x = 19
Since we found x, we can now substitute it into the equation of angle ECD:
4(19) + 3 = 79 = m<ECD (A)

Answer:
Hailey's Work
Step-by-step explanation:
Hailey's work is the correct option for this one because:
- The statement specifies that we need to find the quotient of a number and 7, in that order, and Hailey has written it like this: n/7, making the statement valid.
- Quotient represents division, you will need to divide n by 7 in order to get the quotient.

An expression is shown below:
2x3 + 10x2 − 4x2y − 20xy
Part A: Rewrite the expression so the GCF is factored completely.
The given expression can be rewritten as 2x(x²+5x-xy-10y).
The given expression is 2x³+10x²-2x²y-20xy.
What is GCF?GCF stands for the greatest common factor. The greatest common factor of two numbers is the greatest number that is a factor of both of them.
Now, 2x³=2×x×x×x, 10x²=2×5×x×x, 2x²y=2×x×x×y and 20xy=2×x×x×y
Here, the GCF of all the terms is 2x.
So, the expression becomes 2x(x²+5x-xy-10y).
Therefore, the given expression can be rewritten as 2x(x²+5x-xy-10y).
