Answer: 5x^2 + 3x + 1

Step-by-step explanation:

1.) Put the two equations together into an addition problem.

3x^2 + 4x + 2x^2 - x + 1

2.) Combine like terms.

3x^2 + 2x^2 = 5x^2

4x - x = 3x

1 = 1

3.) Order the like terms together.

5x^2 + 3x + 1

Answer:

i) width = 3.75

length = 4.5

ii) 6.75m^2

iii) 78.75m^2

Step-by-step explanation:

11)

i) Bedroom 1

actual width = 2.5 × 1.5

= 3.75 m

actual length = 3 × 1.5

= 4.5m

ii) Kitchen

actual width = 1.5 × 1.5

= 2.25 m

actual length = 2 × 1.5

= 3 m

actual area = 2.25× 3

= 6 .75 m^2

iii) Apartment

actual width = 5 × 1.5

= 7.5 m

actual length = 7 × 1.5

= 10. 5 m

actual area = 7.5 * 10.5

= 78.75 m ^2

What is the GCF of (8x-6) sos T-T

makvit [3.9K]

Hi student, let me help you out! :)

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

We are asked to find the G.C.F. of 8x-6.

$\triangle~\fbox{\bf{KEY:}}$

G.C.F. stands for Greatest Common Factor.

So what is the G.C.F. of 8x-6? We can list all of their common factors and then select the greatest one, like so:

$\longmapsto\bf{Factors\;of\;8x:}$ 1, 2, 4, 8, x

$\longmapsto\bf{Factors\;of\;-6:}$ -1, 1, 2, -3, 3, -6, 6

So the GCF is:

Now, we can also factor it out by placing it outside the parentheses ():

2(4x-3)

See, we factored it out by dividing both terms of the expression by the G.C.F.

$\ddot\bigstar$ Remember this...

$\fbox{\bf{We\;factor\;out\;the\;G.C.F.\;by\;dividing\;all\;the\;terms\;of\;the\;expression\;by\;it}}$

Hope this helps you out! :D

Ask in comments if any queries arise.
