Find the difference (5a^2+4ab-3b^2)-(-5ab+4b^2+3a^2)

Vesna [10]

Answer:

$\boxed{\bold{2a^2+9ab-7b^2}}$

Step By Step Explanation:

Remove Parenthesis: (a) = a

$\bold{5a^2+4ab-3b^2-\left(-5ab+4b^2+3a^2\right)}$

Simplify $\bold{-\left(-5ab+4b^2+3a^2\right)}$

$\bold{5ab-4b^2-3a^2}$

Rewrite Equation:

$\bold{5a^2+4ab-3b^2+5ab-4b^2-3a^2}$

Simplify $\bold{5a^2+4ab-3b^2+5ab-4b^2-3a^2}$

$\bold{2a^2+9ab-7b^2}$

Write an algebraic equation based on the description. Two angles form a linear pair. The measure of one angle is 24° more than t

IgorC [24]

<h2><u>Answer:-</u></h2>

Given:

Two angles form a linear pair.

It means sum of their measures = 180°.

And,

Measure of one angle is 24° greater than the other.

Let the other angle be x.

→ First angle = (x + 24)

According to the question,

<h3>→ x + x + 24 = 180</h3>

→ 2x = 180 - 24

→ 2x = 156

→ x = 156/2

<h3>→ X = 78°</h3>

<u>There</u><u>fore</u><u>,</u>

1st angle = 78°
2nd angle = 78° + 24° = 102°

Which order pair is a solution of this equation. 5x+y=-25

crimeas [40]

Answer:

(-5,0) or (0,-25) is another solution

Step-by-step explanation:

Do you have a list of choices? If not, you could choose random choices for x and y to determine if they are solutions. Start by letting y = 0. We see that x = -5, so (-5, 0) is a solution to this equation. In fact, it represents the x-intercept of this line. Now, let x = 0. We now see that y = -25, so (0, -25) is another solution to the equation of this line. This coordinate pair is the y-intercept of the line. Try using other values of x and y to see if you can come up with other solutions to this equation.

Which inequality is true? Use the number line to help. A number line going from negative 2.5 to positive 2.5 in increments of 0.

alexgriva [62]

Given:

A number line going from negative 2.5 to positive 2.5 in increments of 0.5.

To find:

The inequality which is true.

Solution:

Consider the number line as shown in the below figure.

We know that, on a line as we go to the left direction, the number become smaller and as we go right, the numbers become larger.

From the number line it is clear that -1.5 is on the left side of 0.5. So,

$-1.5$

Hence, option A is incorrect.

-0.5 is on the left side of 0. So,

$-0.5$

Hence, option B is incorrect.

-1.5 is on the left side of -0.5. So,

$-1.5$

Hence, option C is correct.

One half is equal to 0.5.

$\dfrac{1}{2}=0.5$

Hence, option D is incorrect.
