Answer:

-5 + (-3) < -5 - (-3)

Step-by-step explanation:

so -5 + (-3) evaluates to -5 - 3 which then evaluates to -8, because you're "going back" on the number line by 3.

-5 - (-3) evaluates to -5 + 3 since the negatives cancel out. this further evaluates to -2. this is greater than the previous value so we use the < (if you put this equation on the right side, since you can technically use > if you put the equation on the left side, just depends on what side you put it on)

-5 + (-3) < -5 - (-3)

5x(3x+2)-4(2x-1)<br><br><br><br> Yea i needd help
UkoKoshka [18]

Answer: 15x² + 2x + 4

x = -2/3, 0, 1/2

Step-by-step explanation:

5x(3x + 2) - 4(2x - 1)

First, distribute:

15x² + 10x - 8x + 4

Combine like terms:

15x² + 2x + 4

This is your polynomial!

If you needed to solve for x, take your original factored polynomial and set each term equal to 0:

5x(3x + 2) - 4(2x - 1)

5x = 0

x = 0

3x + 2 = 0

3x = -2

x = -2/3

-4 = 0

No solution

2x - 1 = 0

2x = 1

x = 1/2

x = -2/3, 0, 1/2

Hope this helps!

Which two triangles are similar?
Alla [95]

Answer:

A and C are similar

Step-by-step explanation:

The sum of a triangles angles = 180

If you calculate the remaining angles, you will see that both A and C have the same angles and therefore are similar.

If f(x)=x^2+3x, what is the average rate of change of f(x) over the interval [-2,3]?
Mkey [24]

the average rate of change in the closed interval [ a , b ] is

( f(b) - f(a)))/(b - a)

f(b) = f(3) = 3² + 3(3) = 9 + 9 = 18

f(a) = f(-2) =(-2)² + 3(-2) = 4 - 6 = - 2

= (18 - (-2))/(3 - (-2)) =20/5 = 4

If point E is the midpoint of and point D is the midpoint of , which expression represents the value of s
iogann1982 [59]

The length of ED is half the length of AB.

<h3>What is the length?</h3>
  • Distance is measured by length.
  • Length is a quantity with the dimension distance in the International System of Quantities.
  • Most measurement systems use a base unit for length from which all other units are derived.
  • The meter is the foundation unit of length in the International System of Units.

Reasons:

The given parameters are;

In ΔABC, point E is the midpoint of AC

The midpoint of BC is the point D

Segment ED = s

Segment CE = p

Segment EA = r

Segment CD = q

Segment DB = t

Segment ED = s

Segment AB = u

Required:

The expression that represents the value of s.

Solution:

CE = 0.5 × AC Definition of midpoint

CD = 0.5 × CB Definition of midpoint

Therefore, we have;

\frac{CE}{AC} =\frac{CD}{CB} =0.5

Therefore, given that ∠C ≅ ∠C, by the reflexive property, we have;

ΔABC is similar to ΔCDE by Side-Angle-Side similarity

Which gives;

\frac{CE}{AC} = \frac{CD}{CB}  = \frac{ED}{AB} =0.5=\frac{1}{2}

ED = s and AB = u which gives;

\frac{ED}{AB}=\frac{s}{u}  =0.5=\frac{1}{2}

\frac{s}{u} =\frac{1}{2}

Which gives:

s=\frac{1}{2} *u

The expression that represents the value of s is; s = one-half u

Therefore, the length of ED is half the length of AB.

The question you are looking for is here:

If point E is the midpoint of segment AC and point D is the midpoint of segment BC, which expression represents the value of s? triangle CAB, point E is on segment AC between points A and C and point D is on segment BC between points B and C, creating segment ED, CE equals p, EA equals r, CD equals q, DB equals t, ED equals s, and AB equals u s equals p over q s = one half s equals q over p s = 2u
