Subtract: (2x3+7x2−4)−(2x2+4x−10)

Answers

Answer 1

Answer:

Answer:

-102

Step-by-step explanation:

2x3=6

6+7 = 13

13x2=26

26-4=22

2x2=4

4+4=8

8x-10=-80

-80 - 22 = -102

Hope this helps

Answer 2

Answer:

Final answer:

To subtract the given expressions, first, simplify each expression separately by combining like terms. Then subtract the second expression from the first expression by distributing a negative sign and adding it to the first expression.

Explanation:

To subtract the given expressions, (2x^3+7x^2-4) - (2x^2+4x-10), we need to simplify each expression separately and then subtract them. First, combine like terms within each expression. Then, subtract the terms of the second expression from the first expression. This can be done by distributing a negative sign to each term in the second expression and then adding it to the first expression.

So, (2x^3+7x^2-4) - (2x^2+4x-10) = 2x^3+7x^2-4 - 2x^2-4x+10.

Combining like terms, we get 2x^3+(7x^2-2x^2)+(-4-4x)+(10). Simplifying further, we have 2x^3 + 5x^2 - 4x + 6. Therefore, the result of the subtraction is 2x^3 + 5x^2 - 4x + 6.

Its 5. Since -9 + 8 is in parentheses, you do that first and you should get -1. Finally you add 6 and -1 and you get 5, because you count -1 by 6 since its adding on the number line. Like this, -1, 0, 1, 2, 3, 4, 5. So, the final answer is 5.

Your new cell phone plan costs $45 per month. You pay an extra $0.05 for every text message sent. If you send 60 texts this month, how much will your bill be?

Answers

it would be $48 for that month because if you multiply 0.05 and 60 its 3.00 and then you add 45+3 and get 48

$48 is the cost this month. You multiplied 60 and $0.05, and then added $45.

What number squared equals 50

Answers

The solution is A = √50

The value of the equation is A = √50 or 50^( 1/2 )

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be represented as A

Now , the equation will be

A² = 50 be equation (1)

On simplifying the equation , we get

Taking square roots on both sides of the equation , we get

A = 50 ^ ( 1/2 )

On further simplification , we get

A = √50

The value of A is A = 7.0710678118654752440084436210485

Therefore , the value of A is √50

Hence , the equation is A = √50
