The expressions are not equivalent, even though Ella got the same result when she substituted zero for f. Then the correct option is C.
<h3>What is an equivalent expression?</h3>
The equivalent is the expressions that are in different forms but are equal to the same value.
Ella completed the following work to test the equivalence of two expressions.
First expression, Second expression
⇒ 2f + 2.6 ⇒ 3f + 2.6
⇒ 2(0) + 2.6 ⇒ 3 (0) + 2.6
⇒ 0 + 2.6 ⇒ 0 + 2.6.
⇒ 2.6 ⇒ 2.6
The expressions are not equivalent, even though Ella got the same result when she substituted zero for f.
Then the correct option is C.

Answer:
x = 50°
Step-by-step explanation:
the sum of the exterior angles of any polygon is 360°
2x-12 + 32 + 2x + x + 90 = 360
5x + 110 = 360
5x = 250
x = 50
Step-by-step explanation:
The formula of a volume of a pyramid:

B - base area
H - height
H - height of pyramids
Pyramid A:


Pyramid B:



The volume of the pyramid A is twice as large as the volume of the pyramid B.
The new height of pyramid B: 2H
The new volume:

The volume of the pyramid A is equal to the volume of the pyramid B.
