Answer:
Did you find it?
Step-by-step explanation:
The legs of an isosceles triangle are 7cm longer than the base. Find the legs if the perimeter of the triangle is 38cm.
(38 - 7 - 7) : 3 = <em>8 cm (base)</em>
8 + 7 =
<h2><u><em>
15 cm ( Legs)</em></u></h2>
check
8 + 15 + 15 = 38
the answer is good
Answer:
9/10
Step-by-step explanation:
you find the lowest common denominator in this case is 10
then you take 1/2 and multiply it by 5 both the bottom and top and then you should get 5/10
next you do the same with 2/5 but this time to the get the denominator to 10 you multiply by 2 again multiply both bottom and top and you should get 4/10
now you just add 4/10 and 5/10 together and you get 9/10 or 0.9 as a decimal
