Answer:
12x3+6x2+34x+17
Step-by-step explanation:
(2x+1)(6x2+8+9)
=(2x+1)(6x2+8+9)
=(2x)(6x2)+(2x)(8)+(2x)(9)+(1)(6x2)+(1)(8)+(1)(9)
=12x3+16x+18x+6x2+8+9
=12x3+6x2+34x+17
Answer:
112in²
Step-by-step explanation:
Formulas: V = , V = lwh
Sub: v =
Solve: 32
Sub: v = 4 x 4 x 5
Solve: 80
V = 80 + 32
V = 112
<u>The total volume of the figure is 112in²</u>
The mistake is there is no parenthesis around 4x+12
Answer:
1/4
Step-by-step explanation:
The probability of picking a black ball first is
, because there are 4 black balls and 1 white ball which is 5 balls in total. After picking the first ball, 4 balls remain - 3 black and 1 white, so the probability of picking a white ball is
.
So, the probability of picking a black ball first followed by a white ball is
