Circle=27, triangle=18, and square=26
Start with the second question. If you divide 36 by 2, you get 18 which is the value for the triangle. Now since you know the value of the triange you subtract it from 45. (45-18=27) 27 is the value of the circle. Lastly, subtract 27 from 53 to get the value of the square (53-27=26). Hope this helps!
Answer: Margret grew faster than donovan
Step-by-step explanation:

now you must first distribute the 2 in the brackets. multiply 2 by h and (-29)

now combine "like terms" (-58) with (-58) and 2h with (-h)

now that h has no coefficient (no number in front) you can bring the -116 over to the other side to isolate the variable (h). remember when you bring a number over the equal sign the signs change so (-116) becomes 166.

now add the two terms together

the final result is 157
