Answer:
21x = 14
x = 1.5
Step-by-step explanation:
(-4)3y - 9x = -6
(3)4y - 12x = -8
-12y-9x=-6
12y-12x=-8
0 -21x = -14
-21x/- = -14/-
21x = 14
A)
lets V be the volume and a width, b the base and h height, s the hypotenuse and A the surface area:
V=1/2abh
V=1/2(5.6)(4.6)(7) = 19.16 inch³
B) A=bh+2ls+lb
A=5(7)+2(5.6)(4.6)+(5.6)(5)= 114.52in²
