(s - 5)(2s + 7) =

= 2s² + 7s - 10s - 35 =

= 2s² - 3s - 35

Answer:

2s² - 3s - 35 {final answer}

Step-by-step explanation:

Let's find simplest form of equation,

→ (s - 5)(2s + 7)

→ 2s² + 7s - 10s - 35

→ 2s²- 3s - 35

Thus, the answer is 2s²- 3s - 35.

Answer:

80 degrees i believe

Step-by-step explanation:

if supplementary angles =180 then 180-100=80

Answer:

m∠QRS = 80°

Step-by-step explanation:

We know that, sum of supplementary angles is 180°.

Given that ∠ABC and ∠QRS are supplementary, and m∠ABC = 100°.

So, m∠ABC + m∠QRS = 180°

=> 100° + m∠QRS = 180°

=> m∠QRS = 180° - 100°

=> m∠QRS = 80°

Add the two amounts together:

Step-by-step explanation:

1.  [tex]d = \sqrt{(-3-0)^2+(-2-0)^2}[/tex]

2. [tex]d=\sqrt{(-3)^2+(-2)^2}[/tex]

3. [tex]d=\sqrt{9+4}[/tex]

4. [tex]d=\sqrt{13}[/tex]

[tex]\sqrt{13} = 3.60555..[/tex]

Answer:

d = -4

Step-by-step explanation:

3d – 4 + d = 8d – (-12)

3d - 4 + d = 8d + 12

4d - 4 = 8d + 12

(4d - 4d) - 4 = (8d - 4d) + 12

-4 = 4d + 12

-4 - 12 = 4d (+ 12 - 12)

-16 = 4d

-16/4 = 4d/4

d = -4

Answer:

d= -4

Step-by-step explanation:

3d- 4 +d = 8d + 12

4d - 4 = 8d + 12

4d = 8d + 16

-4d = 16

d= -4

Check

-12 - 4 - 4 = -32 + 12

Answer:

2^3 .3^2

Step-by-step explanation:

if 2×2×2 = 8

and 3×3=9 then 8×9=72

Answer:

2³ × 3²

Step-by-step explanation:

Repeatedly divide by 2 until finish, then divide by 3

72 ÷ 2 = 36

36 ÷ 2 = 18

18 ÷ 2 = 9 , then

9 ÷ 3 = 3

3 ÷ 3 = 1 ← finish when 1 is reached

Then

72 = 2 × 2 × 2 × 3 × 3 = 2³ × 3²

Answer:

∠DAC is 35°

Step-by-step explanation:

Given:

Measure of ∠DAB = 64°

Measure of ∠CAB = 29°

Solution:

∠DAB shows the value of the overall angle.

∠CAB shows the value for almost half of the angle.

∠DAB - ∠CAB = ∠DAC

64° - 29° = ?

∴ 64° - 29° = 35°

Hence, the value of ∠DAC is 35°

Answer:

Step-by-step explanation:

There are 26 friends on his phone.

There's a total of 40 contacts.

P(Friend) = 26/40

P(Friend) = .65

The 10 hypothetical numbers which meets the conditions given on the question may include :

1, 2, 3, 5, 6, 6, 7, 10, 10, 12

The five number summary include the maximum, minimum, lower quartile, Median and upper quartile of a distribution.

The five number summary of the hypothetical data are:

Median: 6

Minimum: 1

Maximum: 12

Lower quartile: 2.75

Upper quartile: 10

Comparing the 5 - number summary of the hypothetical data with that of the given boxplot.

From the given  boxplot shown :

Minimum value = 1

Maximum value = 12

Median = 6

LOWER QUARTILE, Q1 = 4

UPPER QUARTILE, Q3 = 8

IQR = (Q3 - Q1) = 8 - 4 = 4

THE 10 made up numbers :

1, 2, 3, 5, 6, 6, 7, 10, 10, 12

The five number summary for the made up data :

Median = 1/2(n+1)th term = 5.5th term = (6+6)/2 = 6

Minimum: 1

Maximum: 12

First quartile = 1/4(n+1)th = 2.75th term = (2+3)/2 = 2.5

Third quartile: 3/4(n+1)th term = 8.25 = (10+10)/2 = 10

Interquartile Range: (10 - 2.5) = 7.5

Answer:

14

Step-by-step explanation:

If the negative was outside of the lines, then the answer would be -14, but that is not the value. It is 14.

Answer:

D

Step-by-step explanation:

-14 is in Absolute Value signs. This means that if a number is in the absolute value signs, It's always positive. So that leaves us with C, D, or E. Absolute value signs also mean they are the same number as if it was negative, so that tells us that the answer is D!
