Answers

Answer:          36x^3 +27x^2 = 9x^2\left(4x+3\right)

Step-by-step explanation: apply exponent rule rewrite factor out common term plz enjoy

Answer:

[tex]x = 0\; ,-\frac{3}{4}[/tex]

Step-by-step explanation:

[tex]36x^3 + 27x^2 = 0[/tex]

Take 9x² common from the expression on L.H.S.

[tex]=> 9x^2(4x + 3) = 0[/tex]

Here, x will have 2 values :-

1) [tex]9x^2(4x + 3) = 0[/tex]

Divide both the sides by (4x + 3)

[tex]=> \frac{9x^2(4x + 3)}{(4x+3)} = \frac{0}{4x+3}[/tex]

[tex]=> 9x^2 = 0[/tex]

Divide both the sides by 9x

[tex]=> \frac{9x^2}{9x} = \frac{0}{9x}[/tex]

[tex]=> x = 0[/tex]

2) [tex]9x^2(4x + 3) = 0[/tex]

Divide both the sides by 9x²

[tex]=> \frac{9x^2(4x + 3)}{9x^2} = \frac{0}{9x^2}[/tex]

[tex]=> 4x+3 = 0[/tex]

Substract both the sides from 3

[tex]=> 4x+3 -3 = 0 - 3[/tex]

[tex]=> 4x=-3[/tex]

Divide both the sides by 4

[tex]=> \frac{4x}{4} = \frac{-3}{4}[/tex]

[tex]=> x = -\frac{3}{4}[/tex]

Krystal and Danielle each improved their yards by planting daylilies and ivy. They bought their supplies from the same store. Krystal spent $114 on 1 daylily and 12 pots of ivy. Danielle spent $150 on 10 daylilies and 10 pots of ivy. Find the cost of each item.

Answers

Answer:

$9 and $6

Step-by-step explanation:

Let the cost of daylilies = d and ivy = i, then we have below equations:

d + 12i = 11410d + 10i = 150

Simplify the second equation:

d + i = 15

Subtract the second equation from the first:

d - d + 12i - i = 114 - 1511i = 99i = 9, ivy costs $9

Now find d:

d = 15 - 9 = 6, daylilies cost $6

The quotient of a number and 6 minus -1/3 is equal to the quotient of the number and 8. What is the number?

Answers

Answer:

x = 8

Step-by-step explanation:

Let the number = x

x/6 - 1/3 = x/8

-1/3 = x/8 - x/6

-1/3 = (6x-8x)/48

-1/3 = -2/48x

Divide both sides by -2/48

x = -1/3 ÷ -2/48

= -1/3 × -48/2

= 48/6

= 8

x = 8

The number = 8

What angle relationship describes ∠UQR and ∠WRT? segments UV and WZ are parallel with line ST intersecting both at points Q and R respectively Alternate interior angles Alternate exterior angles Corresponding angles Vertical angles

Answers

Answer:

Corresponding Angles

Step-by-step explanation:

I got it right on the test ;)

GOOD LUCK!

The angle ∠UQR and angle ∠WRT are the corresponding angles. Then the correct option is C.

What is an angle?

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.

The segments UV and WZ are parallel with line ST intersecting both at points Q and R respectively.

Then the angle ∠UQR and angle ∠WRT are the corresponding angles.

Then the angle ∠UQR and angle ∠WRT are congruent to each other.

∠UQR = ∠WRT (corresponding angle)

Then the correct option is C.
