Given:

The equation is

4(x-3)+5=17

To find:

The solution of given equation.

Solution:

We have,

4(x-3)+5=17

Using distributive property, we get

4(x)+4(-3)+5=17

4x-12+5=17

4x-7=17

Adding 7 on both sides, we get

4x-7+7=17+7

4x=24

Divide both sides by 4.

x=\dfrac{24}{4}

x=6

Therefore, the value of x is 6.

I need help with this question
nikdorinn [45]
The area of each triangular face is
.. A = (1/2)*b*h
.. Aside = (1/2)*(6 cm)*(5 cm) = 15 cm^2

The area of the triangular base is
.. Abase = ((√3)/4)*s^2 = (√3)/4*(6 cm)^2 = 9√3 cm^2

The total surface area is the base area plus the area of the three sides.
.. Atotal = Abase + 3*Aside
.. = 9√3 cm^2 +3*15 cm^2
.. = (45 +9√3) cm^2
.. ≈ 60.6 cm^2


Actually, there's an error in the picture. The height of the side should be 4, and the length of the edge should be 5. Making that adjustment, the total area is 51.6 cm^2.

It is hard to tell what is intended. Not all answers are showing, so we can't "reverse-engineer" the problem from the answers.

If triangle ABC is dilated using a scale factor of 2, what will be the coordinates of A after the transformation
harkovskaia [24]

Answer:

A' = (-4,4)

Step-by-step explanation:

Given

A = (-2,2)    B = (1,3)       C = (1,0)

k =2 --- scale factor

Required

Determine A'

This is calculated as:

A' = A * k

A' = (-2,2) * 2

A' = (-2 * 2,2 * 2)

A' = (-4,4)
