Can someone please explain this!<br> (-5x^2+3)-(-x^3+9x^2+9)
Anastasy [175]

9514 1404 393

Answer:

  x^3 -14x^2 -6

Step-by-step explanation:

Your expression is the difference of two polynomials. The parentheses can be removed by using the distributive property. The minus sign outside the second set of parentheses applies to each term inside parentheses.

  -5x^2 +3 +x^3 -9x^2 -9

Now, you can group like terms. In "standard form", the degrees of the terms decrease from left to right.

  x^3 +(-5x^2 -9x^2) +(3 -9)

And combine like terms.

  x^3 -14x^2 -6 . . . . . simplified form of the given expression

Angle a =8x+6 <br> Angle b= 4x+38<br> Solve for x and find the measure of angle b
Savatey [412]

Answer:

Angle\ b= 70\°

Step-by-step explanation:

<u><em>The correct question is</em></u>

Angle a and angle b are vertical angles

Angle a =8x+6

Angle b= 4x+38

Solve for x and find the measure of angle b

we know that

<u><em>Vertical Angles</em></u> are the angles opposite each other when two lines cross. They are always congruent.

m∠a=m∠b -----> by vertical angles

substitute the given values

(8x+6)\°=(4x+38)\°

solve for x

8x-4x=38-6

4x=32

x=8

<em>Find the measure of angle b</em>

Angle\ b= (4x+38)\°

substitute the value of x

Angle\ b= (4(8)+38)\°

Angle\ b= 70\°
