Find the area of the regular polygon?

Answer:

The given expression is ,2 - 3 x + 5 + 7(y - 5 x)^{2} + x2−3x+5+7(y−5x)

2

+x

1 . First we will write the term having highest degree and then move to lowest degree,

→ 7 (y -5 x)² + x -3 x+2+5

2. Adding and subtracting like terms

→7 (y -5 x)² - 2 x+7

Expanding the term in brackets

→ 7(y² + 25 x² -10 x y) - 2 x + 7

Use distributive property

→ 7 y² + 175 x² -70 x y -2 x +7→[Wrote the terms from highest degree to lowest degree]

Answer:

D. square the binomial, distribute 7 inside the parentheses, and then combine like terms

Answer:

in the triangle ACB

∠ACB+90+34=180-----> ∠ACB=180-(90+34)----> ∠ACB=56°

∠ACD and ∠ACB-----> are supplementary angles

so

∠ACD+∠ACB=180-----> ∠ACD=180-56----> 124°------> x=124°

the answer Part 1) is x=124°

Part 2)

∠ACB+∠BCF+80=180-----> ∠BCF=180-(∠ACB+80)---> 180-(56+80)

∠BCF=180-136----> 44°-----> y=44°

the answer Part 2) is y=44°

Answer:

Parallel lines have same slope but different y-intercept

None of the given equations have same slope. Therefore lines are not parallel.

Step-by-step explanation:

Slope of Line a: 4y +x=8 is -1/4

Slope of Line b: 2y + x = 4 is -1/2

Slope of Line c: 2y = -3x + 6 is -3/2

Since the slope of the parallel lines is equal and the slope of the given lines is not equal the lines are not parallel.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that, the lines are.

Line a: 4y +x=8

Line b: 2y + x = 4

Line c: 2y = -3x + 6

Line a,

4y +x=8

4y= -x+8

y=-1/4x+2

Compare the given equation with the standard equation, y=mx+c in order to find the value of slope(m).

The slope of line a is -1/4.

Line b:

2y + x = 4

2y=-x+4

y=  -1/2x+2

The slope of line b is -1/2.

Line c:

2y = -3x + 6

y= -3/2x+3

The slope of line c is -3/2

The slopes of the line  4y +x=8, 2y + x = 4 and 2y = -3x + 6 will be -1/4, -1/2 and  -3/2 respectively.

Thus, if the slope of the parallel lines is equal and the slope of the given lines is not equal the lines are not parallel.

Answer:

68

Step-by-step explanation:

Let:

Number of girls invited = x

Number of boys = x +20

3/4 of boy showed up

2/3 of girls showed up

Exactly 19 did not show up

Therefore, we could say:

Fraction of boys that didn't show up = 1 - 3/4 = 1/4

Fraction of girls that didn't show up = 1 - 2/3 = 1/3

That is,

[1/4 *(x + 20)] + [1/3*x] = 19

[(x + 20) / 4] + x /3 = 19

(3(x + 20) + 4x) / 12 = 19

3x + 60 + 4x = 228

7x = 228 - 60

7x = 168

x = 168 / 7

x = 24

Number of girls, x = 24

Number of boys, x + 20 = 24 + 20 = 44

Total friends invited = (24 + 44) = 68

Answer:

2 hours 15 minutes

Step-by-step explanation:

Given that :

Ben's speed = 3 mi/hr

One and half hours after Ben leaves = 1.5 hours

Ben's distance = 3 mi/hr * 1.5 = 4.5 miles

Amanda's speed = 5 mi/hr

Time taken before Amanda catches up:

Let time taken = x

Distance = speed * time

Ben's distance = Amanda's distance

4.5 mi + (3 * x) = 5 * x

4.5 + 3x = 5x

4.5 = 5x - 3x

4.5 = 2x

x = 4.5 / 2

x = 2.25 hours

Time taken = 2.25 * 60 = 135 minutes = 2 hours 15 minutes

It would take Amanda 2.25 hours to catch up with Ben

Speed is the ratio of distance to time. It is given by:

Speed = distance/time

Given that Ben covers a distance d at time t, hence:

3 = d/t

d = 3t

Since Amanda leaves One and a half hours (1.5) after Ben leaves, hence Time = t - 1.5

5 = d/(t - 1.5)

d = 5t - 7.5

Since they catch up, hence:

3t = 5t - 7.5

2t = 7.5

t = 3.75 hours

Time for Amanda = t - 1.5 = 3.75 - 1.5 = 2.25 hours

Hence it would take Amanda 2.25 hours to catch up with Ben.

5x+27=18 minus 27 from both side

5x=-9 divide 5

x=-9/5, in decimal form=-1.8

Answer: The area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides. Quote the actual definition of the Pythagorean theorem.

Pythagorean theorem

in the right angle triangles there is a relationship that governs the length of the three sides. if we knows the length of any two sides, the third side may be calculated by the use of the Pythagorean theorem.

This theorem states that the square on the hypotenuse of a right angled triangle is equal to the sum of the squares on the remaining two sides.

we only use Pythagorean theorem to find the length of the missing side of a right angled triangle only.
