Two fractions have a common denominators of 8. What could the two fractions be?

Answers

Answer 1

Answer: 4 and 8 would be the anwser because 4 x 2 = 8 and then 8x1=8

Answer 2

Answer: The denominator is the bottom number so the answer can be any of 1/8 3/8 5/8 7/8

I made the numerator an odd number because an even number would reduce.

What is the product (2x-1)(x+4)

Answers

Answer: $2x^2+7x-4$ .

Step-by-step explanation:

To find : The product of $(2x-1)(x+4)$

Using distributive property : $a(b+c)=ab+ac$ , we have

$(2x-1)(x+4)\n\n= (2x-1)x+(2x-1)4$

Again , using distributive property : $(b+c)a=ba+ca$ , we have

$(2x-1)x+(2x-1)4=2x\cdot x+(-1)x+2x\cdot 4+(-1)4\n\n=2x^2-x+8x-4\n\n= 2x^2+7x-4$

Hence, The product of $(2x-1)(x+4)$ is $2x^2+7x-4$ .

2x(x+4)-1(x+4)
2x^2+8x-x-4
2x^2+7x-4

(-t^4 – 5t^3– 10t^2) + (9t^3+ 3t^2– 1) =

Answers

According to given question, The simplified polynomial in standard form is: $-t^4 + 4t^3 - 7t^2 - 1$

To add the two polynomials and simplify, we'll combine like terms:

$(-t^4 - 5t^3 - 10t^2) + (9t^3 + 3t^2 - 1)$

In mathematics, a polynomial is an algebraic expression consisting of variables (also known as indeterminates) and coefficients, combined using addition, subtraction, and multiplication operations. The variables are raised to non-negative integer powers, and the coefficients are constants that multiply the variables. The term "polynomial" comes from the Latin words "poly" (meaning "many") and "nomial" (meaning "term").

Step 1: Combine the terms with $t^4 and t^3:$

$(-t^4) + (9t^3 - 5t^3) - 10t^2 + 3t^2 - 1$

Step 2: Combine the $t^3$ terms and the $t^2$ terms:

$(-t^4) + (4t^3) - 7t^2 - 1$

So the simplified polynomial in standard form is:

$-t^4 + 4t^3 - 7t^2 - 1$

Answer:

$- {t}^(4) + 4 {t}^(3) - 7 {t}^(2) - 1$

Step-by-step explanation:

$( - {t}^(4) - 5 {t}^(3) - 10 {t}^(2) ) + (9 {t}^(3) + 3 {t}^(2) - 1) \n = - {t}^(4) - 5 {t}^(3) - 10 {t}^(2) + 9 {t}^(3) + 3 {t}^(2) - 1 \n = - {t}^(4) + 9 {t}^(3)- 5 {t}^(3) + 3 {t}^(2) - 10{t}^(2) - 1 \n = - {t}^(4) + 4 {t}^(3) - 7 {t}^(2) - 1$

Find the slope of the line described by 3x + 2y + 1 = 0. 3/2
−2/3
−3/2
−1/2

Answers

3x + 2y + 1 = 0

subtract 3x+1 from each side

3x + 2y + 1 - 3x -1= -3x -1

2y = -3x-1

divide by 2 on each side

2y/2 = -3x/2 -1/2

y = -3/2 x -1/2

this is in the form y = mx +b where m is the slope

m = -3/2

the slope is -3/2

The prism has a surface area of 1312 mm2.What would the surface area of the prism be if each dimension were halved?

mm2

Prism with a length of thirty-two millimeters, a width of ten millimeters, and a height eight millimeters

Answers

Surface Area = 2(lw + lh + wh)

Divide each dimension by half, and then plug it in to the formula.

32/2 = 18
10/2 = 5
8/2 = 4

Surface Area = 2((4)(5) + (4)(18) + (5)(18))
SA = 2(20 + 72 + 90)
SA = 2(182)

SA = 364

The surface area if each dimension was halved would be 364 mm^2.
