Multiply by 1/3 to reduce.
228*1/3=76m^2
216*1/3=72m^3

Multiply by 4 to increase.
228*4=912m^2
216*4=864m^3

I can explain more if you need.

Answer:

Step-by-step explanation:

From the figure attached,

If the figures shown are congruent (Equal in shape and size), length of all the sides must be equal.

Therefore, sides sides CD and GH must be equal in measures.

Distance between the two points (x_1,y_1) and (x_2,y_2) is given by,

d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Length of the side CD having ends C(-4, 4) and D(0, 5) will be,

CD = \sqrt{(-4-0)^2+(4-5)^2}

CD = \sqrt{(16+1)}

     = \sqrt{17}

Length of GH having ends G(0, -4) and H(4, -5) will be,

GH = \sqrt{(0-4)^2+(-4+5)^2}

      = \sqrt{16+1}

      = \sqrt{17}

Therefore, m(CD) = m(GH)

Similarly, we can prove all corresponding sides of two figures equal in measure.

This shows ABCD ≅ EFGH.

Which must be true of a quadratic function whose vertex is the same as its y-intercept?
BaLLatris [955]

Answer:  Choice A

The axis of symmetry for the function is x = 0.

===========================================================

Explanation:

The vertex is on the axis of symmetry. Since the vertex is on the y axis, this means the y axis itself is the axis of symmetry. The y axis is represented by the equation x = 0. Every point on the y axis has an x coordinate of 0. Example points are (0,2) and (0,5).

This parabola may have 0 roots, 1 root, or 2 roots.

6x + 7y = 13<br> x - 4y=-3<br> Substitution method.
Dovator [93]

Answer:

idk if this is right but if it is right can i have brainliest and if it is wrong then rate me a 1 and you can umm... report me if u want

Step-by-step explanation:

Let's solve for x.

6x+7y=13x

Step 1: Add -13x to both sides.

6x+7y+−13x=13x+−13x

−7x+7y=0

Step 2: Add -7y to both sides.

−7x+7y+−7y=0+−7y

−7x=−7y

Step 3: Divide both sides by -7.

−7x

−7

=

−7y

−7

x=y
