Answer:

x =5

Step-by-step explanation:

2(5x – 2) – 2x– 2 = 34

Distribute

10x-4-2x-2 = 34

Combine like terms

8x -6 = 34

Add 6 to each side

8x-6+6 = 34+6

8x = 40

Divide by 8

8x/8 = 40/8

x =5

Answer:

2x + x + 63 = 180 to find x.

m<1 = 78 degrees

m<2 = 102 degrees

Step-by-step explanation:

Combine like terms: 3x + 63 = 180

Subtraction: 3x = 117

Division: 3x/3 = 117/3

Final Answer: x = 39

m<1 = 2(39) = 78 degrees

m<2 = (39 + 63) = 102 degrees

Check work: 102 + 78 = 180

(180 is the measure of a straight line such as the one represented here)

A cylindrical basin is 2 feet tall and has a diameter of 5 feet, as shown. If the basin is completely filled with water, how muc

jarptica [38.1K]

Answer:

$39.3 ft^3$

Step-by-step explanation:

The cylindrical basin has a height of 2 ft and a diameter of 5 ft.

To find the amount of water that will completely fill up the basin, we simply need to find the volume of the basin.

The volume of a cylinder is given as:

$V = \pi r^2h$

where r = radius of the basin (half the diameter) = 2.5 ft

h = height of the basin

Hence, the volume is:

$V = \pi * 2.5^2 * 2$

$V = 39.27 ft^3$ ≅ $39.3 ft^3$

The cylindrical basin can hold up to $39.3 ft^3$ of water.

Answer:

Step-by-step explanation:

So, when we dilate a triangle, it affects side measures.

So let's find it!

$10*0.4=4$

$30*0.4=12$

So, the sides of our new triangle is 4 and 12.

Let's find the area!

$\frac{4*12}{2} =24$

So, it is the first option! Hope this helps!

Give the domain and range of the relation.<br> y=(x+4)^2-4

Westkost [7]

Answer:

The domain is the interval (-∞,∞)

The range is the interval [-4,∞)

Step-by-step explanation:

we have

$y=(x+4)^2-4$

This is the equation of a vertical parabola in vertex form

The vertex is the point (-4,-4)

The parabola open upward (because the leading coefficient is positive)

The vertex represent a minimum

The domain is the interval (-∞,∞)

The domain is all real numbers

The range is the interval [-4,∞)

$y\geq -4$

The range is all real numbers greater than or equal to -4
