Answer: B. 1.85 + x = 5.30
Explanation:
The starting height of the tree was 1.85 meters. To find the number of meters the tree grew, you would subtract the current height from the previous height.
5.30-1.85=x. This equation is the same as 1.85 + x = 5.30 if you switch the 5.30 and x.
Answer:
x = 17
Step-by-step explanation:
8x+4=7(x+3) - Equation
8x+4=7x+21 - Distribute the 7
8x-7x=21-4 - Isolate the x
x=17 - Answer

Answer:-4,2
Step-by-step explanation:
The answer for PA is 60/13. This is found by
The area of the rectangle is 60, therefore, the big triangle areas are 30 each. We know that the hypotenuse is 13, so therefore, we get
1/2(13*PA) = 30. This then simplifies to
13 * PA = 60, which then turns into
PA = 60/13.
Hope this helps and have a nice day:)
