Which shows a perfect square trinomial?

1 answer:

4 0

Both (m + n)2 and 36 are perfect squares, and 12(m + n) is twice the product of (m + n) and 6. Since the middle term is positive, the pattern is (a + b)2 = a2 + 2ab + b2. Place the x2 tile, 4 x-tiles and 4 1-tiles in the grid. Fill the outside sections of the grid with x-tiles and 1-tiles that complete the pattern.

A rental car company charges $0.50 per mile and a flat rate of $30.00 for any type of sedan. If m represents the number of miles

Umnica [9.8K]

The equation to this would be $0.50m+$30.00=130 because each mile is $0.50 and m would represent as how many miles it well and then adding $30.00 because it’s the flat rate.

Write two addition sentences where the sum is zero. Describe the numbers.

Neko [114]

0+0=0 0+0=0+0

They are all addition, and they are all 0, and since 0 equals nothing, the sum is equivalent to 0!

N = x + y - n = 5 and part two x = u + v = o whats the answer?

Colt1911 [192]

Just substitute the value of x from second equation into first equation:
N = x + y - n = 5
N = u + v + y - n = 5
N = 0 + y - n = 5

In short, N would be equal to y - n which is still equal to 5

Hope this helps!

Solve -2/3x > 8 or -2/3x < 4.

<h3>Answer: Choice C</h3>

{x | x < -12 or x > -6}

=========================================================

Explanation:

Let's solve the first inequality for x.

(-2/3)x > 8

-2x > 8*3

-2x > 24

x < 24/(-2)

x < -12

The inequality sign flips when we divide both sides by a negative value.

Let's do the same for the second inequality.

(-2/3)x < 4

-2x < 4*3

-2x < 12

x > 12/(-2)

x > -6

The conclusion of each section is that x < -12 or x > -6 which points us to choice C as the final answer.

Side note: The intervals x < -12 and x > -6 do not overlap in any way. There's a gap between the two pieces. We consider these intervals to be disjoint. The number line graph is below.

HELPPPP DUE SOON!!! WILL MARK BRAINLYIST AND 10 POINTS

Answer:

688.7

Step-by-step explanation:

Top and Bottom

Area = 3/4 * pi * r^2

r = 6

Area = 3/4 * 3.14 * 6^2

Area = 84.78

Don't round yet.

Vertical surface

Vertical surface = 3/4 * pi * d * h

d = 12 inches (the diameter)

Vertical surface = 3/4 * 3.14 * 12 * 15

Vertical surface = 423.9

Two inner faces

They are both rectangles

Area = 2 * L * W

L = 15

w=6

Area = 2 * 15 * 6 180

Total 688.68

Total = 688.7
