10x-3-2x=4 solve the equation and show your work

Answers

Answer 1

Answer: (10x) (-3) (-2x) = 4
move the -3 to the other side and change the sign
10x - 2x = 4 + 3
8x = 7
therefore x = 7/8

(x+2) is one of the factors of the polynomial x³+13x²+32x+20. Find its remaining factors.A little help....

Answers

Answer:

x^2+11x+10

(x+1)(x+10) since you can factor x^2+11x+10

Step-by-step explanation:

Let's do synthetic division.

We are dividing by x+2, so -2 will be on the outside. Like this:

-2 | 1 13 32 20

| -2 -22 -20

|___________________________

1 11 10 0

The remainder is 0, so (x+2) is indeed a factor of x^3+13x^2+32x+20.

The other factor we found by doing this is (x^2+11x+10).

You can find more factors by factoring x^2+11x+10.

Two numbers that multiply to be 10 and add to be 11 is 10 and 1 so the factored form of x^2+11x+10 is (x+10)(x+1).

Which set of angle measures could be the measures of the interior angles of a triangle? A. 10° 20° and 60° B. 20° 20° and 50°
C. 20° 30° and 50°
D. 20° 60° and 100°

Answers

The 3 interior angles of a triangle when added together need to equal 180 degrees.

The answer would be D. 20° 60° and 100° ( 20 + 60 + 100 = 180)

The width of the Ochoa Community Pool is 20 feet . The length is twice as long as its width. What is the perimeter of the pool?

Answers

Answer:

The perimeter of the pool is 120 feet.

Step-by-step explanation:

width of the Ochoa community pool = 20 feet

length is twice as long as its width = 2(20) = 40 feet

Use this formula to get perimeter = 2(w) + 2(L)

then the perimeter equals to = 2(20)+ 2(40)

= 40 + 80 = 120 feet

The perimeter of the pool is 120 feet.

the width is 20 feet the length is 20 feet x 2 = 40 and I bet you know how to work out the perimeter add all the width and length so 20 + 20 +40 + 40 =120 120 feet is the answer your welcome

What is the equation of the line that passes through the points (5,2) and (-5,7)

Answers

Written in y=mx+b form: m is the slope and b is the y-intercept.First you need to use the two points to find the slope, the formula is $m=(y_(2)- y_(1))/(x_(2) -x_(1))$ .

$m=(7-2)/(-5-5)=(5)/(-10)=-(1)/(2)$

So now to find the y-intercept, You can use either or of the (x,y) points since the answer will be the same, but for this I'm going to use (5,2).

$b=2-(-(1)/(2))(5)=(9)/(2)$

Now that we have the slope and the y-intercept, we can put it together to make the equation $y=-(1)/(2) x+(9)/(2)$ .

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)

if a circle is inscribed in a square with a perimeter of 24 cm., what is the circumference of the circle?

Answers

The circumference of the circle is 6.28 cm.

What is Circle?

Circle is a two dimensional figure which consist of set of all the points which are at equal distance from a point which is fixed called the center of the circle.

Perimeter of a square is the length of it's boundary.

Perimeter of a square = 4a, where a is the side length.

4a = 24 cm

a = 24 / 4

a = 6 cm

If a circle is inscribed in a square, diameter of the square is same as the side length of square.

Diameter, d = 6 cm

Radius, r = d / 2 = 3 cm

Circumference of a circle is the length of it's boundary.

Circumference = 2 π r

= 2π × 3

= 6π
