Answer:

9

Step-by-step explanation:

<u><em>Definition of: Coefficient</em></u>

A number used to multiply a variable.

<u><em>Example:</em></u> 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.

Variables with no number have a coefficient of 1.

<u><em>Example</em></u>: x is really 1x.

<em><u>coefficients:</u></em>

3<em>x⁴</em>+ 5<em>x²</em> + 1<em>x</em>

<u><em>sum of the coefficients:</em></u>

3 + 5 + 1

8 + 1

irina [24]

Answer:

New bed dimension of bed 0.5 ft, 0.25 ft

New bed dimension of room 1.16 ft, 1.33 ft

Step-by-step explanation:

Given data:

bed dimension is given as 6 ft by 3 ft

room dimension is given as 14 ft 16 ft

according to the given information , new dimension of the room and bed will be 1/12 times of actual dimension. therefore we have

New bed dimension of bed = \frac{1}{12} \times 6 ft, \frac{1}{12} \times 3 ft

                                 = 0.5 ft, 0.25 ft

New bed dimension of room = \frac{1}{12} \times 14 ft, \frac{1}{12} \times 16 ft

                                                 = 1.16 ft, 1.33 ft

The sum of 5 consecutive integers is 110.<br>What is the fourth number in this sequence?​
Brut [27]

<u>Given</u>:

The sum of 5 consecutive integers is 110.

Let the sequence be x, x + 1, x + 2, x + 3, x + 4

We need to determine the fourth number in the sequence.

<u>Value of x:</u>

Since, the sum of 5 consecutive integers is 110.

Thus, we have;

x+x+1+x+2+x+3+x+4=110

Adding the like terms, we have;

5x+10=110

       5x=100

         x=20

Thus, the value of x is 20.

<u>Fourth term:</u>

The fourth term of the sequence is x + 3

Substituting x = 20 in the term, we get;

Fourth term = 20 + 3 = 23

Thus, the fourth term of the sequence is 23.

rusak2 [61]
It travels 2144 in 8 hours.

Therefore, if you want to find out how many miles it travels in one hour, divide 2144 by 8.

2144 ÷ 8 = 268 miles in one hour. :)

A triangle has sides with lengths of 5x-7,3x-4 and 2x-6. What is the perimeter of the triangle?
boyakko [2]
The perimeter is the sum of all the sides, so P = (5x -7) + (3x-4) + (2x -6). Then group like terms so you have p = 5x + 3x + 2x -7-4-6 and end up with P = 10x - 17
