Primitevly do it like:
6v-13v-18=-81
- 7v= -63
v=9
P.S Strongly recommend to learn algebra's basics
L= 6cm
The square root of a number is the factor that we can multiply by itself to get that number. Square root is the opposite of square of the number.
√36 = √6×6= 6
so you can write L = √36 = 6cm now you can find the area.
The correct answer is c, 370
You need to add 1 and 5 and get 6
do 150 divided by 6
you get 25
