Mathematics
1 answer:
Ede4ka [16]2 years ago
5 0

Answer:maybe this helps

Step-by-step explanation: k*(x)-(2*x^2+7)=0

STEP

1

:

Equation at the end of step 1

kx - (2x2 + 7) = 0

STEP

2

:

Trying to factor a multi variable polynomial

2.1 Factoring kx - 2x2 - 7

Try to factor this multi-variable trinomial using trial and error

Factorization fails

Equation at the end of step

2

:

kx - 2x2 - 7 = 0

STEP

3

:

Solving a Single Variable Equation:

3.1 Solve kx-2x2-7 = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

We shall not handle this type of equations at this time.

I don’t know how to find the LCM for this.
nekit [7.7K]

Answer:

B

Step-by-step explanation:

7mn³|7m²n³ ---14mn^5

       | m---2n²

LCM=7mn³×m×2n²

=14m²n^5

or LCM of 7,14 =14

Highest power of m=2

Highest power of n=5

LCM=14m²n^5

the area of a room in a dollhouse is 1248 square inches. the width of the room is 8 inches. how long is the room
zaharov [31]
The dollhouse is 156 inches long.

Area is computed by multiplying the length to its width.

A = L * W

Use the formula and substitute the values given in the problem.
A = 1248 sq. inches
w = 8 inches
L = ?

1248 = L * 8

L = 1248 sq. in/ 8 in
L = 156 inches

If x = 45, y = 63, and the measure of AC = 4 units, what is the difference in length between segments AB and AD? Round your answ
brilliants [131]

Answer:

  1.17 units

Step-by-step explanation:

From the definition of the sine of an angle, you know ...

  sin(45°) = AC/AB = 4/AB   ⇒   AB = 4/sin(45°) ≈ 5.6569

  sin(63°) = AC/AD = 4/AD   ⇒   AD = 4/sin(63°) ≈ 4.4893

Then the difference AB-AD is ...

  AB -AD = 5.6569 -4.4893 = 1.1676

  AB -AD ≈ 1.17 units
