What is the answer of this expression?

Answers

Answer 1

Answer:

|-21 + 5| = 16

Answer 2

Answer:

16

Step-by-step explanation:

The absolute value function always gives a positive value, that is

| - a | = | a | = a , thus

| - 21 + 5 | = | - 16 | = 16

help please! I just want to actually get my homework done​

Answers

Answer:

72/b = h

Step-by-step explanation:

plug in known values

A = 1/2 (bh)

36 = 1/2 (bh)

goal is to isolate the variable h (height)

multiply both sides by 2 to cancel out 1/2

36 × 2 = 1/2 × 2 (bh)

72 = bh

divide both sides by b (base)

72/b = bh ÷ b

72/b = h

i dont see the value for base given so this would be the final answer as far as i know

Need help urgently with this geometry question

Answers

Answer: Choice B) x = 52

=======================================================

Explanation:

The angles (2x+24) and x are same side interior angles. Same side interior angles are supplementary when we have parallel lines.

(2x+24) + (x) = 180

2x+24+x = 180

3x+24 = 180

3x = 180-24

3x = 156

x = 156/3

x = 52

Congruent triangles are similar triangles.

The statement that completes the proof is [tex]\mathbf{\angle ACB \cong ECD}[/tex]

From the complete question (see attachment), we have the following highlights

[tex]\mathbf{AC\cong CE}[/tex].[tex]\mathbf{BC\cong CD}[/tex]

The angle at point C of both triangles are congruent

i.e. [tex]\mathbf{\angle ACB \cong ECD}[/tex]

This means that the missing statement of the proof is that the angles at C of both triangles are congruent.

Hence, the statement that completes the proof is [tex]\mathbf{\angle ACB \cong ECD}[/tex]

C =

Answers

Answer:

c = 208.8

Step-by-step explanation:

a. [tex]\frac{c}{7.2} =29[/tex]   To solve for C, you need to get the variable on one side of the equation and the numbers on the other side of the equation.

b.  [tex]\frac{c}{7.2} =29[/tex]   You need to move the 7.2 to the other side. So, multiply both sides by 7.2, because it's being divided, so multiplying will cancel it out.

c:  [tex]c = 29 * 7.2[/tex]   Then, multiply 7.2 by 29. (The * symbol means multiply)

d.  c. = 208.8   The answer is 208.8, which is rounded to the tenths place.

What is product of 5.2 · 10^6 and 1.4 · 10^3

Answers

Answer:

7280000000 or 7.28^9 (in scientific notation)

Step-by-step explanation:

this question is asking you to transfer numbers out of scientific notation and multiply them. 10^6 is 1 followed by 6 zeros (good trick to remember) or 1000000. when you multiply anything by a power of 10 you just add that many zeroes to it or move the decimal point one point to the left for every zero. so in this example it is 5.2 times 1000000 which is 5200000. we do the same for the other one and we get 1400. When we multiply these two values we get 7280000000 or 7.28^9

Completely factor the following polynomial: 8x^3−125

Answers

Answer:

(2x-5)(4x^2+10x+25)

Explanation:

Factoring difference of cubes (a3−b3): (a−b)(a2+ab+b2)

Here, a is 2x because the cube root of 8 is 2 and the cube root of x3 is x, b is 5 because the cube root of 125 is 5.

Plug the numbers in:

(2x−5)((2x)2+2x⋅5+52)

(2x−5)(22x2+10x+25)

(2x−5)(4x2+10x+25)
