Answer:

B. n + 9

Step-by-step explanation:

Given:

n² + 3n - 54

Let's factorize

n² + 9n - 6n - 54

n(n + 9) -6(n + 9)

(n - 6)(n + 9)

Therefore, out if the options given, n + 9 is the expression of the factor of n² + 3n - 54.

Answer:

Exact form would be like this, y=3, -1/6

Decimal form would be like this, y=3, -0.16666666666666666666666 and keep adding 6's.

Step-by-step explanation:All you do is isolate the variable by dividing each side by factors that don't contain the variable. Sorry I took so long I'm trying to answer multiple problems at once. Hope this helps you out.    :   )

Answer:

The correct answer is given by option a.

Step-by-step explanation:

Rational roots theorem:

In the rational roots theorem, we take the leading coefficient(which multiplies the term of x with the highest exponent) and the independent term(which does not multiply any value of x).

The possible roots have the format p/q, in which p are the factors of the independent term, and q are the factors of the leading coefficient.

In this question:

Leading coefficient: 3

Independent term: 15

Factors of the independent term: {1, 3, 5, 15} -> p

Factors of the leading coefficient: {1,3} -> q

Possible roots:

All possible values, positive or negative, in which p is divided by q. So

[tex]\pm \frac{1}{1}, \pm \frac{1}{3}, \pm \frac{3}{1}, \pm \frac{3}{3}, \pm \frac{5}{1}, \pm \frac{5}{3}, \pm \frac{15}{1}, \pm \frac{15}{3}[/tex]

So, without the repeated terms, they are:

[tex]\pm \frac{1}{3}, \pm \frac{5}{3}, \pm 1, \pm 3, \pm 5, \pm 15[/tex]

The correct answer is given by option a.

Answer:

10x+4y+10z Hope I helped? :')

Steps for answer!

1. Expand by distributing terms.

6x+8y+10z+4(x-y)

2. Expand by distributing terms.

6x+8y+10z+4x-4y

3. Collect like terms.

(6x+4x)+(8y-4y)+10z

4. Simplify.

10x+4y+10z

the correct answer is,

[tex]x = \frac{121}{25} [/tex]

if you want me to solve without the parentheses then the answer would be,

[tex]x = \frac{1609}{100} [/tex]

Answer:

a) £58.5

b) £117

c) £438.75

Step-by-step explanation:

Mr Singh is paid £11.70 per hour after tax is deducted.

This means that for x hours of work, his earning are given by:

[tex]E(x) = 11.7x[/tex]

a) How much does he earn if he works 5 hours?

This is E(5).

[tex]E(5) = 11.7*5 = 58.5[/tex]

b) How much does he earn if he works 10 hours?

This is E(10).

[tex]E(10) = 11.7*10 = 117[/tex]

c) He works 37.5 hours per week. How much does he earn in a week?

This is E(37.5).

[tex]E(37.5) = 11.7*37.5 = 438.75[/tex]

Answer:

7 feet

Step-by-step explanation:

Let's find how many feet did the tree gain during 5 1/2 years:

51 - 12.5 = 38.5

Now devide this number by 5 1/2 to find average length tree gained yearly:

38,5 / 5.5 = 7

Answer:

(C) Sophie used the wrong height for the pyramid.

Step-by-step explanation:

she should have subtracted 4 from 30 because that was apart of the prism

The total volume is 7448  cubic millimeters. Sophie has made mistake in copying height of pyramid.

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

Given that, a rectangular prism with a length of 28 millimeters, width of 21 millimeters, and height of 4 millimeters.

Volume of rectangular prism = Length×Width×Height

= 28×21×4

= 2352 cubic millimeters

A rectangular pyramid with a base of 28 millimeters by 21 millimeters and height of 26 millimeters.

Volume of a rectangular pyramid = (lwh)/3

= (28×21×26)/3

= 15288/3

= 5096 cubic millimeters

Total volume = 2352+5096

= 7448  cubic millimeters

Hence, Sophie has made mistake in copying height of pyramid.

Answer:

Step-by-step explanation:

by solving inequality :

so the value of x should be less than 73.

so required values are 70 and 60

70 and 60 are the correct answers. If you take 70 and subtract 3 you get 67, which is less than 70. If you take 60 and subtract 3 you have 57, which is less thna 70. Basically any number that is 72 or less would be a coorect answer
