The product of x and the sum of 6 and 8 times the square of x
Kamila [148]

Let's separate this problem into several parts:

1. The product of x

AND

2. The sum of 6 and 8

TIMES

3. The square of x

So translating this word problem into numbers, we have:

x TIMES (6+8) TIMES x²

so that is:

x * 14 * x²

which is:

14x^(2+1) = 14x³

ladessa [460]

Answer:

1195.22N.

Step-by-step explanation:

Mass: m =82.6 kg

Velocity: v= 16.4m/sec.

Distance: d = 9.29 metres.

Acceleration = (v²/2d) = (16.4²/18.58) = 14.47m/sec².

Force = (mass x acceleration) = (82.6 x 14.47) = 1195.22N.

c. 35 + 50x ≤ 1,325

Step-by-step explanation:

Abbey's total cost must be less then or equal to her total savings, i.e.

cost ≤ savings

it is given that cost = fixed registration fee and a monthly fee of $50 per month. Hence,

fixed registration + (monthly fee)*(number of months) ≤ savings

let the number of months be x,

hence
