Rewrite in simplest terms: (-x+8y)+(-10x-6y)(−x+8y)+(−10x−6y)

Answers

Answer 1

Answer:

Answer:

10x² - 48y² - 11x + 2y - 74xy

Step-by-step explanation:

(-x+8y)+(-10x-6y)(−x+8y)+(−10x−6y)

Rearranging,

=> - x - 10 x + 8y - 6y + (-10x-6y)(−x+8y)

=> - 11x + 2y + 10x² - 48y² + 6xy - 80xy

=> 10x² - 48y² - 11x + 2y - 74xy

Can someone show me how to factor this? 5k-35

Answers

Sure.
Can you find a number that goes into both terms, 5k and 35 ?
How about 5 ?

(5k - 35) = 5 times (k - 7) .

$5k-35=5(k-7)$

3a³ + 2b³ = ?

Substitute for values:

3a³ + 2b³
a = 3
3 × 3³ + 2b³

b = 2
3a³ + 2 × 2³

Full question:

3 × 3³ + 2 × 2³

3 × 3³ + 2 × 2³
3 × 27 + 2 × 2³
3 × 27 + 2 × 8
81 + 16
97

The value of the expression 3a³ + 2b³ when a = 3 and b = 2 is 97.

3 × 3³ + 2 × 2³ = 97

Two buildings on opposites sides of a highway are 3x^3- x^2 + 7x +100 feet apart. One building is 2x^2 + 7x feet from the highway. The other building is x^3 + 2x^2 - 18 feet from the highway. What is the standard form of the polynomial representing the width of the highway between the two building?

Answers

Given:

Distance between two buildings = $3x^3- x^2 + 7x +100$ feet apart.

Distance between highway and one building = $2x^2 + 7x$ feet.

Distance between highway and second building = $x^3 + 2x^2 - 18$ feet.

To find:

The standard form of the polynomial representing the width of the highway between the two building.

Solution:

We know that,

Width of the highway = Distance between two buildings - Distance of both buildings from highway.

Using the above formula, we get the polynomial for width (W) of the highway.

$W=3x^3- x^2 + 7x +100-(2x^2 + 7x)-(x^3 + 2x^2 - 18)$

$W=3x^3- x^2 + 7x +100-2x^2-7x-x^3 -2x^2+18$

Combining like terms, we get

$W=(3x^3-x^3)+(- x^2 -2x^2-2x^2)+ (7x -7x)+(100 +18)$

$W=2x^3-5x^2+0+118$

$W=2x^3-5x^2+118$

Therefore, the width point highway is $2x^3-5x^2+118$ .

The correct standard form of the polynomial equation that represents the width of the highway between the two buildings is: $2x^3-5x^2+118$ .

Given:

Distance between the building: $3x^3-x^2+7x+100$
