Volume of a rectangular prism is ~

\sf{Volume_{cuboid}= Length × Width × Height}

\qquad \sf  \dashrightarrow \: v = (4x + 2) \times (3x - 5) \times (7x + 4)

\qquad \sf  \dashrightarrow \: v = (12 {x}^{2} - 20x + 6x - 10) \times (7x + 4)

\qquad \sf  \dashrightarrow \: v = (12 {x}^{2} - 14x- 10) \times (7x + 4)

\qquad \sf  \dashrightarrow \: v = 84 {x}^{3}  + 48 {x}^{2}  - 98x {}^{2}  - 56x - 70x - 40

\qquad \sf  \dashrightarrow \: v = 84 {x}^{3} - 50 {x}^{2}  -  126x - 40

So, the correct choice is B

Question 4 (5 points)
klemol [59]

Answer: B (-2)

Step-by-step explanation:

[log base b of a = c] turns into [b^c = a]

You have log base 5 of 1/25 = ?, so it turns into 5^? = 1/25

This part is sort of guess and check, but we can look at it to find the answer pretty easily. First, it's 1/n, so we should use a negative power: 5^-1 = 1/5

In addition to being in the denominator, it's 25, which is 5^2.

So, if we want to put it in a reciprocal as well as square it, we can use -2:

5^(-2) = 1/(5^2) = 1/25

Since -2 (B) is the exponent we place on 5 to get 1/25, it is also the answer to log base 5 of 1/25.

Devon set out to bicycle from Exeter to the beach, a distance for 10 miles. After going a short while at 15 miles per hour, the
enyata [817]

Answer:

Distance between Exeter and the point where flat tire occurred was 1.875 miles.

Step-by-step explanation:

Let the distance of Exeter and the point where bike developed the flat tire was = x miles

Then time taken to reach that point with speed 15 mi per hour = \frac{\text{Distance traveled}}{\text{Time taken}}

= \frac{x}{15} hours

Devon comes back with a speed of 3 miles per hour then time taken to come back = \frac{x}{3} hours

Total time for the entire episode = 48 minutes or \frac{3}{4} hours

Therefore, \frac{x}{15}+\frac{x}{3}=\frac{3}{4}

\frac{x+5x}{15}=\frac{3}{4}

\frac{6x}{15}=\frac{3}{4}

x = \frac{3}{4}\times \frac{15}{6}

x = \frac{15}{8} miles

x = 1.875 miles

Therefore, distance between Exeter and the point where flat tire occurred was 1.875 miles.
