Round 8.043 to the nearest hundredth

Answers

Answer 1
Answer: Rounding to the nearest hundredth would make the answer be: 8.04. Just move the digits over twice to the right and if the number is 5 or greater(for the number 3), the answer would have been: 8.05. But since it is a 3(lower than 5), then the answer would just be 8.04. 
Hope this helps! :-)
Answer 2
Answer: It is 8.because you look at the 4 cuz it is in the hundredths place the you look at the 3 if it is 4 or less take it away if it is 5 or more add 1. It's less so take everything away that is behind the decimal

Express your answer in simplest terms.

A. 4 1/4


B. 4 1/8


C. 5 5/8


D. 6 1/4

Answers

we can solve this by multiplying those two numbers but we place them in improper fraction.

2 1/2 x 2 1/4
becomes
5/2 x 9/4

for fraction multiplication, just multiply numerator by numerator and denominator by denominator

5/2 x 9/4 = 45/8

we can simplify this into mixed fraction while numbers in whole numbers and remainder in numerator

5 5/8 is the answer

What is the product of two algebraic expressions?

When two algebraic expressions are multiplied, the result is called the product, and the two expressions making up the product are called factors and multiplicands.

The multiplication of two algebraic equations can be expressed as a × b.

The product of 3a + 5 and 2a2 + 4a – 2 is determined in the following steps given below.

\rm =(3a + 5) *( 2a^2 + 4a -2)\n\n= 3a ( 2a^2 + 4a -2) +5( 2a^2 + 4a -2)\n\n =6a^3+12a^2-6a+10a^2+20a-10\n\n=6a^3+22a^2+14a-10\n

Hence, the product of  3a + 5 and 2a2 + 4a – 2 is \rm 6a^3+22a^2+14a-10\n.

Answer:

6a3 + 22a2 + 14a - 10

Step-by-step explanation:

(3a + 5) x (2a^2 + 4a - 2)

= 3a(2a^2 + 4a - 2) + 5(2a^2 + 4a - 2)

= 6a^3 + 12a^2 - 6a + 10a^2 + 20a - 10

= 6a^3 + 22a^2 + 14a - 10
