Hello There!
Step-by-step explanation:
Equivalent expressions are expressions that work the same even though they look different.
Examples of two equivalent expressions are:
-4(x + 2) and 4x + 8
-2y+5y−5+8 and 7y+3
These are equivalent expressions as they have the same value.
hope this helps,have a great day!!

Answer:
Step-by-step explanation:
Add all the marbles up. Find the answer. Then you will have to divide the number of marbles with the number of jars then you will have your answer.
Note that a squared pyramid has a square base & 4 equal triangles.
To find the lateral the lateral area you calculate the area of the 4 equal triangles and to find the surface area (total Area) you add the area of the base:
Area of each triangle = side (5) x slant (9) and you divide by 2
==>Aera of 1 triangle = (9x5)/2 = 45/2 & for the 4 triangles
Lateral area = (45/2) x 4 = 90 in²
Now the base area (square) = 5 x 5= 25 in²
so the surface area = 90+25 = 115 in² (answer a)
Answer:
55°
Step-by-step explanation:
35°+ 90° + ? =180°
? = 180° - 125°
= 55°
