8 percent of 84000 is 6720 add 2500 equals 9220
Answer:
C
Step-by-step explanation:
A net is formed when the surfaces of a given shape is laid flat on a horizontal plane. And on folding it with respect to its edges, the initial shape is reproduced with no distortion or loss.
From the given question, the net that would not produce a cube is that of option C.
Each Had 10. Y= 4. Because 3 x 4 = 12 + 8 = 20 ÷ 2 = 10
Answer:
Step-by-step explanation:
1 In general, given a{x}^{2}+bx+cax
2
+bx+c, the factored form is:
a(x-\frac{-b+\sqrt{{b}^{2}-4ac}}{2a})(x-\frac{-b-\sqrt{{b}^{2}-4ac}}{2a

2 In this case, a=1a=1, b=-2b=−2 and c=-2c=−2.
