Answer:
B 2.25
Step-by-step explanation:
Answer: 4x+8
Step-by-step explanation:
Okay since the area for the block is X, two numbers multiplied together is X.
Since the big block has an area of X^2, then this shows the sides to be X.
This gives the sides of the block with area X to be 1 and X.
Now just add up every side like this : 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + x + x + x + x to get 4x+8
The answer for 5. is y+5. In an isosceles triangle, 2 of the sides are congruent. If the base is 4y+2, the other 2 sides must equal to 2y+10. Since both sides are congruent the only answer would be y+5.
Hope that helped :))))
