What’s the product of 3x(x² + 4)?

Mathematics
1 answer:
klio [65]3 years ago
5 0

Answer:

3x³ + 12x

Step-by-step explanation:

3x is 3 times x. If we multiply x times x², we get x³. This is because x² can be written as x·x, so if we multiply x by that, we get x·x·x. Since we are multiplying x² by 3x, we get 3x³. Now, we multiply 3x by 4, this gets us 12x. Now, we write it out as 3x³ + 12x.

A. Convert 74.35° to degree, minute and second
elena-14-01-66 [18.8K]

Answer:

74°21'

Step-by-step explanation:

<u><em>DMS Form:</em></u>

The given angle is 74.35°

<em><u>The whole number part is the degree so we don't need to change that. While, the decimal part would be multiplied  by 60 to convert it into minutes.</u></em>

=> 74° + (0.35 × 60)

=> 74° + 21'

<u><em>Since, the minute form has already been changed into a whole number and it doesn't contain any further decimal part, so we won't change it further to seconds. So, our answer will be</em></u>

=> 74°21'

The value of x is 3. The correct option is the third option- 3

The width of the backyard is 9 yards. The correct option is the first option-  9 yards

<h3>Perimeter of a Rectangle </h3>

From the question, we are to determine the value of x

13.

Perimeter of a rectangle = 2 (l + w)

Where l is the length

and w is the width

From the given information,

Perimeter = 24 cm

In the given diagram,

l = 3x cm

w = 3 cm

Thus,

24 = 2(3x + 3)

24 = 6x + 6

6x = 24 - 6

6x = 18

x = 18/6

x = 3

Hence, the value of x is 3. The correct option is the third option- 3

14.

From the given information,

The width of the yard is 3 less than 4 times the length

That is,

w = 4l - 3 --------- (1)

Also,

Perimeter = 24 yards

∴ 24 = 2(l + w) ---------- (2)

Put equation (1) into (2)

24 = 2(l + w)

24 = 2(l + 4l - 3)

24 = 2(5l - 3)

24 = 10l - 6

10l = 24 + 6

10l = 30

l = 30/10

l = 3 yards

Substitute the value of l into equation (1) to get w

w = 4l - 3

w = 4(3) - 3

w = 12 - 3

w = 9 yards

Hence, the width of the backyard is 9 yards. The correct option is the first option-  9 yards
