Find the value of x and check the solution.
5 + 4x = -11​

Answers

Answer 1

Answer:

x=-4

Step-by-step explanation:

5+4x=-11

4x=-11-5

4x=-16

x=-16/4

x=-4

5+4(-4)=-11

5-16=-11

-11=-11

Answer 2

Answer:

x = -4

Step-by-step explanation:

5 + 4x =  -11

4x = -11 - 5

4x = -16 (Divide 4 both sides)

x = -4

5 + 4x =  -11

5 + 4(-4) = -11

5 - 16 = -11

-11 = -11

What is the coefficient in the expression 4x + 2
O2
O4
Ox
O+​

Answers

A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x).

The 2 and + are out since they don't have variables(and the + is just a +).

So 4 and x are left. x is a variable, not a coefficient, so the last(and correct) answer is 4.

The circumference of a circle is m. What is the area , in square meters ? Express your answer in terms of pi

Answers

Answer:

area = m²/2π

Step-by-step explanation:

∵ circumference of circle = 2πr = m

∴ r = m/2π

∵ area of circle = πr²

∴ area of circle = (m/2π)² × π = m²/2π² × π = m²/2π

Answers

9514 1404 393

Answer:

  about 106.5 units

Step-by-step explanation:

The length of each side is found using the distance formula:

  d = √((x2-x1)^2 +(y2-y1)^2)

For example, the length of side AB is ...

  d = √((9 -2)^2 +(1 -3)^2) = √(7^2 +(-2)^2) = √53 ≈ 7.28

The other side lengths are calculated the same way. The sum of side lengths of the given triangle is ...

  AB +BC +CA = 7.28 +13.34 +14.87 = 35.49

__

Multiplying each coordinate by 3 effectively dilates the triangle by a factor of 3 about the origin. That increases the perimeter by a factor of 3, so it is ...

  3(35.49) ≈ 106.5 . . . . units

Please help me with the question please ASAP ASAP I’m begging please

Answers

Answer: a= 144. b= 67

Step-by-step explanation:

Angle b and the angle of measure 113 are same side interior angles which sum to 180 (When 2 parallel lines are cut by a transversal, special angles are formed)

113+b=180. Subtract 113 from both sides.

b= 67 degrees

Now that you have b, the interior angles of four sided figures sum to 360.

a+113+67+36=360. Combine like terms.

a+216=360. Subtract 216 from both sides.

a= 144 degrees

A number when divided by 5 gives 0 as remainder, that number when divided by 7 gives 0 as remainder also. What will be the remainder when that number is divided by 35?

Answers

Answer:

zero

Step-by-step explanation:

The computation of the remainder when the number would be divided by 35

Let the number be x

So if x is divided by 5 gives the remainder 0

x = 0

And, if x is divided by 7 gives the remainder 0

x = 0

So if x is divided by 35 so the remainder is also zero
