If HCF (6,x)n = 2 and LCM(6,x) = 60 , Find x^2+3x

Step-by-step explanation:

We know:

We have:

HCF(6, x) = 2 and LCM(6, x) = 60.

Substitute:

60 · 2 = 6 · x

120 = 6x             divide both sides by 6

20 = x → x = 20

Substitute to x² + 3x:

20² + 3(20) = 400 + 60 = 460

step-by-step explanation:

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.
