Remmeber you can do anything to an equaiton as long as you do it to btoh sides
5-6(a+2)=7+a
distribute
5-6a-12=7+a
add like terms
-6a-7=7+a
add 6a both sides
-7=7+7a
minus 7 both sides
-14=7a
divide by 7
-2=a
a=-2
Answer:
To find the missing base, you simply divided the area by the given height. This will work the same way if you are looking for the height. To find the missing height, divide the area by the given base.
Step-by-step explanation:
base = 35cm, height = ? cm, and a = 700 cm^2 a = bh
700 = 35 x h
700/35 = 35 x h/35
20 = h
Therefore, the answer would be 20cm. Hope this helps! :)
