Simplify the expression:
2(3 + 2m)

Answers

Answer:

4m + 6

Step-by-step explanation:

Hello There!

We can simplify the expression by distributing the 2 to what is inside of the parenthesis ( 3 and 2m)

3 * 2 = 6

2 * 2m = 4m

so the expression 2(3 + 2m) simplified would be

4m + 6

Answer: 6+4m

Step-by-step explanation:

Let's take our equation first

2(3+2m)

Now we need to distribute the 2 into the parenthesis'

This would mean we need to multiply 2 by 3 and 2m

our answer would be

6+4m

Can someone pls help me

Answers

Answer:

Step-by-step explanation:

∠A + ∠B + ∠C = 180 {Angle sum property of triangle}

∠A + 65 + 55 = 180

∠A + 120 = 180

∠A = 180 - 120

∠A = 60

If two triangles are similar, then the corresponding angles of two triangles are congruent.

z = ∠A

z = 60

Solution -:

In ∆ ABC,

[tex]\angle[/tex] A + [tex]\angle[/tex] B + [tex]\angle[/tex] C = 180° .... (Angle sum property of a triangle)

Here, we have:

[tex]\angle[/tex] B = 65°

[tex]\angle[/tex] C = 55°

Substituting values,

[tex]\dashrightarrow\sf{\angle A + 65 + 55 = 180} \\ \\ \dashrightarrow\sf{\angle A + 120 = 180} \\ \\ \dashrightarrow\sf{\angle A = 180 - 120} \\ \\ \dashrightarrow{\boxed{\sf{\gray \angle A = 60 \: \bigstar}}}[/tex]

As we know that,

★ If two triangles are similar, then the corresponding sides of two triangles are congruent.

[tex]\longrightarrow\tt{z= \angle A } \\ \\ \longrightarrow{\boxed{\tt{\gray Z = 60 \: \bigstar}}}[/tex]

Answers

The calculated length of V'B' in the reflection of triangles is (c) 5

How to determine the length of V'B'

From the question, we have the following parameters that can be used in our computation:

The triangle and the image

Also, we know that the triangles are reflected

The reflection transformation is a rigid transformation

This means that

V'B' = VB

From the figures, we have

VB = 5

So, we have

V'B' = 5

Hence, the length of V'B' is (c) 5

Solve the equation and enter the value of x.

X = ?

Answers

11x + (-4x) =56
7x=56
x=8

Answer:

[tex] \sf \: x = 8[/tex]

Step-by-step explanation:

Given equation,

→ 11x + (-4x) = 56

Now the value of x will be,

→ 11x + (-4x) = 56

→ 11x - 4x = 56

→ 7x = 56

→ x = 56/7

→ [ x = 8 ]

Hence, the value of x is 8.

Answers

Answer:b

Step-by-step explanation:

Option B will be the correct option.

Given in the question,

Radius of the cylindrical jar = 2 inchesHeight of the jar = 5 in.Height of the jelly in the jar = (5 - 0.5) = 4.5 inches

Expression for the volume of a cylinder = [tex]\pi r^{2}h[/tex]

= [tex]\pi (2)^2(4.5)[/tex]

= [tex]18\pi[/tex]

= 18(3.14)

= 56.52

≈ 57 in³

Therefore, Option B is the correct option.

hypotenuse = √(3√2)² + (3√2)²

hypotenuse = √18 + 18

hypotenuse = √36
