1 answer:
expeople1 [14]3 years ago
8 0

Answer:

Step-by-step explanation:

x - 2y = 14

x + 3y = 9

subtract the first equation from the second to eliminate the x terms:

x + 3y = 9

-x + 2y = -14

-----------------

 5y = -5

y = -1

x - 2(-1) = 14

x = 12

:::::

y = 2x

5x - y = 9

Substitute 2x for y in the second equation?:

5x - 2x = 9

3x = 9

x = 3

y = 6

Use the formula S A = 6s2 , where S A is the surface and s is the edge length of the cube , to solve his problem.
Gennadij [26K]
To find the surface area of the cube using the formula, you would substitute in 2 1/2 for the length of the side.

SA = 6 x 2.5 x 2.5
SA = 37.5 ft.²

You are finding the area of one face (2.5 x 2.5) and multiplying it by six because there are six groups of this.

Find the common difference of the arithmetic sequence, the next three terms, the equation, and the term given for 8, 10, 12, 14
fredd [130]

Answer:

see explanation

Step-by-step explanation:

In an arithmetic sequence the common difference d is

d = a₂ - a₁ = 10 - 8 = 2

To obtain the next term in the sequence add d to the previous term, that is

a₅ = 14 + 2 = 16

a₆ = 16 + 2 = 18

a₇ = 18 + 2 = 20

The next 3 terms in the sequence are 16, 18, 20

The n th term equation for an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 8 and d = 2, thus

a_{n} = 8 + 2(n - 1) = 8 + 2n - 2 = 2n + 6
