Answer:

140x^2−384x+37

Step-by-step explanation:

(10x+−1)(14x+−37)

=(10x)(14x)+(10x)(−37)+(−1)(14x)+(−1)(−37)

=140x^2−370x−14x+37

Answer:

X=9

Step-by-step explanation:

Pull out like factors :

  -4x + 36  =   -4 • (x - 9)

 Solve :    -4   =  0

This equation has no solution.

A a non-zero constant never equals zero.

 Solve  :    x-9 = 0

Add  9  to both sides of the equation :

                     x = 9

Answer:

13

Step-by-step explanation:

here's your solution

=> base = 12

=> perpendicular = 5

=> we need to find hypotenuse = ?

=> we know , h^2 = p^2 + b^2

=> h^2 = 12^2 + 5^2

=> h^2 = 144 + 25

=> h^2 = 169

=> h= √169

=> h= 13

Answer: Simplifying

4x + 50 = 6x + 20

Reorder the terms:

50 + 4x = 6x + 20

Reorder the terms:

50 + 4x = 20 + 6x

Solving

50 + 4x = 20 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

50 + 4x + -6x = 20 + 6x + -6x

Combine like terms: 4x + -6x = -2x

50 + -2x = 20 + 6x + -6x

Combine like terms: 6x + -6x = 0

50 + -2x = 20 + 0

50 + -2x = 20

Add '-50' to each side of the equation.

50 + -50 + -2x = 20 + -50

Combine like terms: 50 + -50 = 0

0 + -2x = 20 + -50

-2x = 20 + -50

Combine like terms: 20 + -50 = -30

-2x = -30

Divide each side by '-2'.

x = 15

Simplifying

x = 15

Answer: y = 800

Step-by-step explanation:

3(y + 200) = 3000

3y + 3(200) = 3000

   3y + 600 = 3000

              3y  = 2400     [Subtract 600 from both side]

                y   = 800      [Divide 3 in both side to solve for y]

Answer:

1/2 or .5

Step-by-step explanation:

Hey There!

So the first step of this problem is to get y on one side and everything else on the other side

to do so we use inverse operations

so to get rid of the 2x we subtract 2x from each side

we would end up with -4y=5-2x

now want to get rid of the -4 on the y

to do so we would divide each side by -4

we would end up with

[tex]y=\frac{1}{2}x -\frac{4}{5}[/tex]

so we can conclude that the slope is 1/2 or .5

Answer:

[tex]\huge\boxed{\sf x = 3 }[/tex]

Step-by-step explanation:

Given that

f(x) = 4x + 5

Put f(x) = 17

17 = 4x + 5

Subtract 5 to both sides

17 - 5 = 4x

12 = 4x

Divide 4 to both sides

12 / 4 = x

3 = x

OR

x = 3

Answer: 17/21

Step-by-step explanation:

Number of cities = 42

Fraction of cities that has lake = 5/42

Fraction of cities that have rivers = 29/42

The fraction of these 42 cities that have a lake or river running through them will then be:

= 5/42 + 29/42

= 34/42

= 17/21

Answer:

Acute triangle

Step-by-step explanation:

All the three angles of the triangle is less than 90, all angles are acute. So, it is acute triangle.

If any one of the three angles is 90, then it is right triangle.

If any one of the three angle is more than 90, then it is obtuse triangle.

Answer:

4

Step-by-step explanation:

okay since there was a 50% INCREASE, 6 is (100%+50%) greater than last months amount.

100%+50%=150%=1.5

let's say that x is last months amount

6=1.5x

x=6/1.5

x=4

There were 4 musicians in the band last month.

Answer:

14 marble

Step-by-step explanation:

here's your solution

=> Total number of marble = 35

=> ratio of David and Jason = 2 : 3

=> let the ratio be in x

=> now, 2x + 3x = 35

=> 5x = 35

=> x = 35/5

=> x = 7

=> number of marble with David = 7*2 = 14

=> number of marble with Jason = 7*3 = 21

hope it helps

Answer:

number of marbles that David had=

[tex]35 \times \frac{2}{5} \\ 14marbles[/tex]

Answer:

True.

Step-by-step explanation:

It is given that, a regular hexagon is dilated by a scale factor of 0.4 to make image.

It means, the perimeter of image is 0.4 times the perimeter of the original hexagon.

For example,

Let's take the rectangle with length of 12 and width of 4, it's perimeter is 12+12+4+4 =32

Let's find image using scale factor 0.4, we get

length =0.4(12)= 4.8

width =0.4(4)=1.6

So, perimeter of image = 4.8+4.8+1.6+1.6=12.8

If we compare the perimeters

0.4(32)=12.8.

So, it is true.
