x(4x + 1). Need helpppp

Answer: 14

Step-by-step explanation:

110 + 110 + 70 + 5x= 360 ( total number of angles in a quadrilateral is 360 degrees)

290+5x= 360

5x= 360 - 290= 70

x= 70/5= 14

Answer:

0.006 L

Step-by-step explanation:

Mass of water = 6kg

Using the relation :

Density = mass / volume

Density of water = 100kg/m³

1000 kg/m³ = 6kg / volume

1000kg/m³ * volume = 6kg

Volume = 6kg / 1000 kg /m³

Volume = 0.006

9514 1404 393

Answer:

  a, b

Step-by-step explanation:

This has to do with correctly using the distributive property to distribute a negative multiplier.

a) (5p -7) -(3p +1) = 5p -7 -3p -1 = (5-3)p +(-7-1) = 2p -8 . . . . true

__

b) (10b +3) -(-2b +78) = 10b +3 +2b -78 = (10+2)b +(3 -78) = 12b -75 . . . . true

__

c) (4h +2) -(h -6) = 4h +2 -h +6 = (4-1)h +(2+6) = 3h +8 . . . . not 3h-4 (false)

Step-by-step explanation:

step 1. 4x + 27 + 3x = 90 (definition of a rectangle)

step 2. 7x = 63 (collect like terms. subtract 27 from both sides)

step 3. x = 9 (divide both sides by 7)

Answer: D

Step-by-step explanation: its best you can get to the a quotient (from Latin: quotiens "how many times", pronounced) is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division (in the case of Euclidean division), or as a fraction or a ratio (in the case of proper division). For example, when dividing 20 (the dividend) by 3 (the divisor), the quotient is 6 in the Euclidean division sense, and 62/3 in the proper division sense.

Answer:

[tex]L_c=25.12ft[/tex]

Step-by-step explanation:

From the question we are told that

Width of circular path [tex]w_c=4ft[/tex]

Inner Diameter [tex]d_i_n=550ft[/tex]

Outer diameter [tex]d_{out}= 550 +2*4[/tex]  (inner diameter +  2 circular path width)

[tex]d_{out}= 550 +8\\d_{out}= 558ft[/tex]

Generally the equation for inner circumference of the circle [tex]C_1[/tex] is mathematically given by

[tex]C_1=\pi d_{in}[/tex]

[tex]C_1=3.14*550[/tex]

[tex]C_1=1727ft[/tex]

Generally the equation for outer circumference of the circle [tex]C_2[/tex] is mathematically given by

[tex]C_2=\pi d_{out}[/tex]

[tex]C_2=3.14*558[/tex]

[tex]C_2=1752.12ft[/tex]

Generally the difference in length of the two circumference [tex]L_c[/tex] is mathematically given by

[tex]L_c=C_2-C_1[/tex]

[tex]L_c=1752.12-1727[/tex]

[tex]L_c=25.12ft[/tex]

Answer:

This is your answer.......

The length of the ramp that is on the ground is 72 inches.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Ramp scale drawing dimension:

Height = 1 in

Length = 12 in

Now,

1 in = 6 inches

12 in = 6 x 12 = 72 inches

Thus,

The length of the ramp is 72 inches.

Answer: m∠E = 55°

Step-by-step explanation: If a triangle has two equal sides, it is called Isosceles. Another characteristics of this type of triangle is that the angles opposite the equal sides are also congruent.

Triangle ΔEFG has two sides with approximately the same length:

[tex]\overline{GE}[/tex] ≈ [tex]\overline{FG}[/tex]

So, it is an isosceles.

Therefore the opposite angles are m∠E and m∠F.

m∠E = m∠F

m∠E = 55°

Angle at vertex E is 55°.

Answer:

910

Step-by-step explanation:

From the given information;

Suppose that everyone served together;

Then, we have:

= C(8,3) × C(6,3)

= [tex]\dfrac{8!}{3!(8-3)!}\times \dfrac{6!}{3!(6-3)!}[/tex]

= [tex]\dfrac{8!}{3!(5)!}\times \dfrac{6!}{3!(3)!}[/tex]

= 1120

But since 1 man and 1 woman refuses to serve together;

Then:

The combination will be:

= C(7,2) × C(5,2)

= [tex]\dfrac{7!}{2!(7-2)!}\times \dfrac{5!}{2!(5-2)!}[/tex]

= [tex]\dfrac{7!}{2!(5)!}\times \dfrac{5!}{2!(3)!}[/tex]

= 210

∴

1120-210 = 910

Thus, the number of ways committee can be formed = 910

Answer:

7(4 + y)

Step-by-step explanation:

so it's a square which means all of the sides are equal.

that means x+7=3x+1

      subtract 1 from both sides

x + 6 = 3x

      subtract x from both sides

6 = 2x

      divide both sides by 2

3 = x

you can do the same for y

2y - 1 = -3y + 14

    add 3y to both sides

5y - 1 = 14

     add 1 to both sides

5y = 15

      divide both sides by 5

y = 3
