Resolver la siguiente ecuación por eliminación o sustitución: a-8b= -9 a-2b= -7

Solution: and .

Step-by-step explanation:

The given pair of equations:

Eliminate equation (i) from (ii) , we get

Put value of b in (ii) , we get

Solution: and .

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
