=x(x +8)+5(x + 8)

=x^2+8x+5x+40

=x^2+13x+40

2)(x-1)(x+3)

=x(x+3)-1(x+3)

=x^2+3x-1x-3

Answer: 35

Step-by-step explanation:

Answer:

7 Gallons every minute

Step-by-step explanation:

We know that a total of 42 gallons of water was pumped for 6 minutes at a constant rate. Constant rate means that it will always pump the exact same amount of water each time. Eince its at a constant rate we just need to find out how much water was poured over the course of a minute, which can be done by dividing 6 (minutes) by 42 (gallons of water) = 7 gallons of water.

Answer:

x + 6x+10   + x+2 = 180

x = 21

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

x + 6x+10   + x+2 = 180

Combine like terms

8x + 12 = 180

Subtract 12 from each side

8x+12-12 = 180-12

8x =168

Divide each side by 8

8x/8 = 168/8

x =21

Answer:

Step-by-step explanation:

by angle sum property of a triangle ,

x+x+2+6x+10=180

8x =180-12

8x =168

x =168/8

x=21

Answer:

You can use our formula for the surface area of a rectangular prism for a cube as well. A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.

Answer:

x=-4

Step-by-step explanation:

Ohhh you wrote 4 on the other post, not 4x.

Okay.

6(x+3)-4x=10

6x+18-4x=10

2x=-8

x=-4

Answer:

The value of [tex]x[/tex]:

[tex]x = -4[/tex]

Step-by-step explanation:

Solve for [tex]x[/tex]:

[tex]6(x+3) - 4x = 10[/tex]

Use Distributive Property:

[tex]6(x+3) - 4x = 10[/tex]

[tex]6x + 18 - 4x = 10[/tex]

Combine [tex]6x[/tex] and [tex]-4x[/tex] together:

[tex]6x + 18 - 4x = 10[/tex]

[tex]2x + 18 = 10[/tex]

Subtract both sides by [tex]18[/tex]:

[tex]2x + 18 - 18 = 10 -18[/tex]

[tex]2x = -8[/tex]

Divide both sides by [tex]2[/tex]:

[tex]\frac{2x}{2} = \frac{-8}{2}[/tex]

[tex]x = -4[/tex]

So, therefore, the final answer is [tex]x = -4[/tex] .

Answer:

x =3.

Step-by-step explanation:

This is an isosceles triangle  so the 2 sides opposite the equal angles are congruent.

So  3x + 2 = 11

3x = 9

x = 3.

Answer:

49 and 2/3

Step-by-step explanation:

3x+2+18+11=180

3x+31=180

3x=149

x=49 and 2/3

[tex]\large \boxed{36\sqrt{2}\text{ units}}[/tex]

Step-by-step explanation:

Assume ∆DEF looks like the one below.

We can use Pythagoras' Theorem to find the hypotenuse f.

[tex]\begin{array}{rcl}d^{2} + e^{2} & = & f^{2}\\36^{2} + 36^{2} & = & f^{2}\\f^{2} & = & 2 \times 36^{2}\\f & = & \sqrt{2 \times 36^{2}}\\& = & 36\sqrt{2}\\\end{array}\\\text{The length of the hypotenuse is $\large \boxed{\mathbf{36\sqrt{2}}\textbf{ units}}$}[/tex]

Answer:

The x-coordinate of A is:

a = 6.1

Step-by-step explanation:

For point A:

x-coordinate = a

x-coordinate + y-coordinate = 14

y-coordinate = 14 - x-coordinate

y-coordinate = 14 - a

So point A can be written as (a, 14-a)

Let (a,14) be (x₁,y₁)

Point P can be written as (3a, a²+13a-11)

Let P be (x₂,y₂)

Slope of a line passing through 2 point is given as:

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

where m=7

Substitute all values

[tex]7=\frac{(a^2+13a-11)-(14-a)}{3a-a}\\7=\frac{a^2+13a-a-11-14}{3a-a}\\7=\frac{a^2+12a-25}{2a}\\14a=a^2+12a-25\\a^2-2a-25=0\\a=6.1,a=-4.1[/tex]

As A has only positive coordinates

a = 6.1

Answer:

c = 2500

Step-by-step explanation:

[tex]x^2+100x + c\\x^2+2\times 50\times x + (50)^2\\=x^2+2\times 50\times x + 2500\\=x^2+100 x + 2500\\equating \: it \: with\: \\x^2+100x + c\\we\; find:\\c = 2500[/tex]

Answer:

c = 2500

Step-by-step explanation:

x² + 100x + c  where c = ?

100 x :    100x / 2x = 50

(50)² = 2500

Answer:

17 units

Step-by-step explanation:

The radius r is the distance from the centre of the circle to a point on it.

To calculate r use the distance formula

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 7, - 1) and (x₂, y₂ ) = (8, 7)

r = [tex]\sqrt{(8+7)^2+(7+1)^2}[/tex]

  = [tex]\sqrt{15^2+8^2}[/tex]

  = [tex]\sqrt{225+64}[/tex]

   = [tex]\sqrt{289}[/tex]

   = 17
