Step-by-step explanation:

Kosi traced a rectangle on a coordinate grid. The rectangle had the following vertices: (−6, 5), (2, 5), (2, –1), and (–6, –1). Which of the following numbers are dimensions of the rectangle? Select each correct answer. A. 4 units B. 5 units C. 6 units D. 7 units E. 8 units F. 9 units. help, please!.

When given vertices for a geometric shapes we find the lengths of the side by using the formula:

When(x1, y1) and (x2, y2)

= √(x2 - x1)² + (y2 - y1)²

A= (−6, 5),B = (2, 5), C = (2, –1), and D = (–6, –1).

For AB

A= (−6, 5),B = (2, 5),

= √(2 -(-6)² + (5 - 5)²

= √8² + 0

= √64

= 8 units

For BC

B = (2, 5), C = (2, –1),.

√(2 - 2)² +(-1 - 5)²

= √0 + -6²

= √36

= 6 units

For CD

C = (2, –1), and D = (–6, –1).

= √(-6 -2)² + (-1 -(-1))²

= √-8² + 0²

= √64

= 8 units

For AD

A= (−6, 5), D = (–6, –1).

= √(-6 -(-6))² + (-1 - 5)²

= √0² + -6²

= √36

= 6 units

Therefore, the following numbers that are dimensions of the rectangle is

C) 6 units

E) 8 units

Answer:

Length of the rectangular lot = 60 meters

Width of the rectangular lot = 30 meters

Step-by-step explanation:

Let the width of the rectangular lot be x meters.

So, Length of the same = 2x metres.

[tex]A(rectangular \:lot) = (2x)(x)[/tex]

[tex]\implies A(rectangular \:lot) = 2x^2[/tex]

When length is increasEd by 40 m and width by 6 m. Then....

New length = [tex](2x + 40) \:m[/tex]

New width =[tex](x + 6) \:m[/tex]

According to the question:

[tex](2x + 40)(x + 6) = 2(2x^2)[/tex]

[tex]\implies 2x(x + 6) + 40(x + 6) - 4x^2=0[/tex]

[tex]\implies 2x^2+12x + 40x + 240 - 4x^2=0[/tex]

[tex]\implies 2x^2- 4x^2+12x + 40x + 240 =0[/tex]

[tex]\implies -2x^2+52x + 240 =0[/tex]

[tex]\implies 2(x^2-26x - 120) =0[/tex]

[tex]\implies x^2-26x - 120=0[/tex]

[tex]\implies x^2-30x+4x - 120=0[/tex]

[tex]\implies x(x-30)+4(x - 30)=0[/tex]

[tex]\implies (x-30)(x+4)=0[/tex]

[tex]\implies x-30=0,\: x+4=0[/tex]

[tex]\implies x=30,\: x=-4[/tex]

Since, x represents the side length, so its value can't be negative.

[tex]\implies x=30[/tex]

[tex]\implies 2x=2(30)=60[/tex]

Thus,

Length of the rectangular lot = 60 meters

Width of the rectangular lot = 30 meters

Answer:

At least 7 since 0 is a whole number the lowest n+7 can be is 0+7= 7 and there is seven numbers in between 0 and seven.

Step-by-step explanation:

Answer:

(4x^2-3)(x^2-5)

Step-by-step explanation:

We are going to group the first two and last two terms and find the GCF of each set.

4x^4-20x^2-3x^2+15

(4x^4-20x^2)(-3x^2+15)

4x^2(x^2-5)-3(x^2-5)

Then we group the GFCs together and the rest

(4x^2-3)(x^2-5)

Answer:

I think it's 12 bro, I'm not sure

Answer:

His pattern is 42cm long.

Step-by-step explanation:

Each repetition of the pattern is 8 cm (4 colors time 2cm each)

If the last color is red and he painted 6 red strips in total, then he repeated the pattern 5 times and ended on an extra red strip.

So 8cm times 5 repetitions equals 40, plus 2cm for the extra red strip.

72/(8 - 9)  Be sure and use brackets when you post a question. 8 - 9 = - 1

72/-1 = - 72

2 - 72 = - 70

Answer:

  3(5h - 2g)

= 3×5h - 3×2g  

= 15h - 6g

  5(12g - 4f)

= 5×12g - 5×4f

= 60g - 20f

  2(h - 3g)

= 2×h - 2×3g

= 2h - 6g

  4(3x - g) + 4x

= 4×3x - 4×g + 4x

= 12x - 4g + 4x

= 16x - 4g

  9(4g + 1) - 5g

= 9×4g + 9×1 - 5g

= 36g + 9 - 5g

= 31g + 9

Answer:

C

Step-by-step explanation:

Rotates then reflects over the y axis.

Answer:

C) rotation, then reflection

Step-by-step explanation:

1. rotates to spot 2. then reflects to spot 3.

Answer:

Step 1: Add 2 to both sides.

7x−2+2=−9+2

7x=−7

Step 2: Divide both sides by 7.

7x/7  =  -7/7

Answer:  x=−1

Answer:

x=-1

Step-by-step explanation:

7x-2=-9 (Given)

7x=-7 (Add 2 on both sides to eliminate he -2 on the left side)

x=-1 (Divide both sides with 7 to eliminate the 7 in 7x)

Answer: x=-1

Given:

The given rule is

[tex]f(n)=n^3-7[/tex]

Domain of the function is the set of whole numbers greater than 0.

To find:

The first 4 terms of the sequence.

Solution:

We have,

[tex]f(n)=n^3-7[/tex]

Domain of the function is the set of whole numbers greater than 0. So, the domain for first four terms of the sequence are 1, 2, 3 and 4 respectively.

For n=1,

[tex]f(1)=(1)^3-7[/tex]

[tex]f(1)=1-7[/tex]

[tex]f(1)=-6[/tex]

For n=2,

[tex]f(2)=(2)^3-7[/tex]

[tex]f(2)=8-7[/tex]

[tex]f(2)=1[/tex]

For n=3,

[tex]f(3)=(3)^3-7[/tex]

[tex]f(3)=27-7[/tex]

[tex]f(3)=20[/tex]

For n=4,

[tex]f(4)=(4)^3-7[/tex]

[tex]f(4)=64-7[/tex]

[tex]f(4)=57[/tex]

Therefore, the first 4 terms of the sequence are -6, 1, 20, 57 respectively.

Find x-intercept

The x-intercept is where the graph crosses the x-axis. To find the x-intercept, we set y1=0 and then solve for x.

3x + y = 16

3x + 1(0) = 16

x1 = 5.333 y1 = 0

Find y-intercept

The y-intercept is where the graph crosses the y-axis. To find the y-intercept, we set x2=0 and then solve for y.

3x + y = 16

3(0) + y = 16

y2 = 16 x2 = 0

Answer:

t=2

Step-by-step explanation:

Start by subtracting 9 from both sides. You'll get 7-2t=3/2t. I made 3/2 a mixed number, so 1 1/2. You should have 7-2t=1 1/2t. Add 2t to both sides, because the 2t is negative. You should have 7=3 1/2t. Last step is to divide     3 1/2 into both sides. 7 divided by 3 1/2 is equal to 2, so t=2

Hey there!

7/8÷6/8=?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

7/8×8/6=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

7×8/8×6=56/48

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 56 and 48 using

GCF(56,48) = 8

56÷8/48÷8=76

The fraction

7/6

is the same as

7÷6

Convert to a mixed number using

long division for 7 ÷ 6 = 1R1, so

7/6= [tex]1 \frac{1}{6} [/tex]

Therefore:

7/8÷6/8= 1 1/6

Let's do

[tex]\\ \bf\hookrightarrow \dfrac{7}{8}\div \dfrac{6}{8}[/tex]

[tex]\\ \bf\hookrightarrow \dfrac{7}{8}\times \dfrac{8}{6}[/tex]

[tex]\\ \bf\hookrightarrow \dfrac{7}{8}\times \dfrac{4}{3}[/tex]

[tex]\\ \bf\hookrightarrow \dfrac{7}{2}\times \dfrac{1}{3}[/tex]

[tex]\\ \bf\hookrightarrow \dfrac{7}{6}[/tex]
