Answer:

[tex]\implies x = (-2) \qquad or\qquad x = \dfrac{-3}{2}[/tex]

Step-by-step explanation:

Given :-

And we need to find out the roots of the given equation. We can use the middle term splitting method to find out the roots as ,

Given equation :-

[tex]\implies 2x^2 + 7x +6=0[/tex]

Step 1: Find out the factors of 12 :-

We will choose the two factors such that their sum equals to the coefficient of x i.e. 7 .The factors are , 1×12 , 2×6 , 3×4 .

Step 2 : Breaking the middle term :-

[tex]\implies 2x^2 + 3x+4x +6=0[/tex]

Step 3: Take out common from terms :-

[tex]\implies x(2x + 3) +2(2x +3)=0[/tex]

[tex]\implies ( x +2)(2x+3)=0 [/tex]

Step 4 : Equate them with 0 :-

[tex]\implies x = (-2) \qquad or\qquad x = \dfrac{-3}{2}[/tex]

Hence the correct options are C and D .

Answer:

The answer is D. 47 meters.

Answer:

The missing exponent is 12.

Step-by-step explanation:

Whenever you divide same-base exponents, you keep the base numbers the same and subtract the exponents.

The only number subtracted by 4 that would give you 8 is 12.

Or, if the numbers are larger, it is must easier to add the exponent in the answer to the number in the equation.

For example,

[tex]17^4+17^8=17^1^2[/tex]

Therefore, the missing exponent is 12.

Because:  [tex]17^1^2/17^4=17^8[/tex]

Answer: 500 meters

Step-by-step explanation:

Since he won the gold medal in the men’s 500 m kayak race, with a time of 1 min 37.9 s, the speed will be:

= Distance/Time

= 500m/1 min 37.9s

= 500m/97.9s

= 5.11m/s

Since he also won the bronze medal in the 1000 m race, with a time of 3 min 28.2s, the speed will be:

= Distance/Time

= 1000/3 min 28.2s

= 1000m/208.2s

= 4.80m/s

Therefore, he rowed with greater speed in the 500 meters.

Note that 60seconds = 1 minute

Answer:

mode in class 8A = 157 cm

mode in class 8B = 176 cm

median in class 8B = 165 cm

range in class 8A = 173-148= 25 cm

• many students class 8A are taller than class 8B

• the tallest student is in class 8B

Answer:

19.1 cm

Step-by-step explanation:

the other side = √8.1²-7.1²=√65.61- 50.41

= √15.20 = 3.9

perimeter = 7.1+8.1+3.9= 19.1 cm

Balanced force is two forces pushing the same amount on different sides of an object. If you and a friend tried pushing a table from either side with the same amount of force, it wouldn’t move.

Answer = 3/4

First, change them all into like fractions.

-2, -11/4, -7/2 = -8/4, -11/4, -14/4

Therefore the common difference of their arithmetic sequence is 3/4

Answer:

11

Step-by-step explanation:

217 = 19x + 8

209 = 19x

x = 209/19

x = 11

Answer:

height / shadow = height / shadow until sun moves or earth tilts

12/9 = h / 6

h = 6*12 /9 = (3*2*3*4 ) / (3*3) = 2 * 4 = 8

So C. 8ft

Answer:

11/16 inch or 0.6875 inch

Step-by-step explanation:

26 * x = 17 7/8

17 7/8 = 143/8

143/8 ÷ 26 = 143/8 x 1/26 = 143/208 = 0.6875

0.6875 in = 11/16 in

Complete Question

A highway makes an angle of 6 degrees with the horizontal. This angle is maintained for a horizontal distance of 8 miles

To the nearest hundredth of a mile, how high does the highway rise in this

*mile section?

Answer:

[tex]h=0.84miles[/tex]

Step-by-step explanation:

From the question we are told that:

Angle [tex]\theta = 6 \textdegree[/tex]

Horizontal distance traveled [tex]d=8miles[/tex]

Generally the Trigonometric equation for Height  is mathematically given by

[tex]Tan \theta=\frac{h}{5}[/tex]

[tex]h=8*tan(6)[/tex]

[tex]h=0.84miles[/tex]

Answer:

[tex]x = 6 \sqrt{3} [/tex]

Step-by-step explanation:

[tex]x = \sqrt{ {12 }^{2} - {6}^{2} } = 6 \sqrt{3} [/tex]

Step-by-step explanation:

Well assuming P represents the number of outcomes, n the number of competitors and r the number of places to be awarded.

P = n!

    (n−r)!

P=30! /

     (30-4)!

P=30!/26!

P=657720
