Answer:

B,E and F

Step-by-step explanation:

(B)A cross section parallel to the base is a square measuring 4 cm by 4 cm.

Since a cube has <u>equal base length</u>, any cross section parallel to the base will also have an equal base length.

(E)A cross section perpendicular to the base through the midpoints of opposite sides is a square measuring 4 cm by 4 cm.

Since a cube has <u>equal side lengths</u>, any cross section parallel to the side will also have an equal base length.

(F)A cross section that passes through the entire bottom front edge and the entire top back edge is a rectangle measuring 4 cm by greater than 4 cm.

Using Pythagoras Theorem

$4^2+4^2=4\sqrt{2}>4$

There the cross section will be a rectangle which measures $4\sqrt{2}\:cm\:by\:4\:cm$

How do you solve equations by substitution

Jet001 [13]

Answer: The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.
