<span>Simplifying 4x + 2y = 18 Solving 4x + 2y = 18 Move all terms containing y to the left, all other terms to the right. Add '-4x' to each side of the equation. 4x + -4x + 2y = 18 + -4x Combine like terms: 4x + -4x = 0 0 + 2y = 18 + -4x 2y = 18 + -4x Divide each side by '2'. y = 9 + -2x Simplifying y = 9 + -2x

Find the perimeter of the following trapezoid:<br> 6 ft<br> 2.5 ft/ 12 ft<br> 2.5 ft<br> 8 ft

sasho [114]

Answer:

31ft

Step-by-step explanation:

6 ft + 2.5 ft + 12 ft + 2.5 ft + 8 ft = 31ft

I assumed the slash in the space between 2.5ft and 12ft was an error, so I ignored it in the solution to this problem.

Besides that, perimeter is found by adding all sides of the shape or figure together, and the sum of that is the perimeter.

The basic formula for perimeter is:

base + height + base + height.

I do not think you square perimeter as you do area (e.g. 31ft^2).

The given question is a quadratic equation and we can use several methods to get the solutions to this question. The solution to the equation are 3/4 and -5/6 and the greater of the two solutions is 3/4

<h3>Quadratic Equation</h3>

Quadratic equation are polynomials with a second degree as it's highest power.

An example of a quadratic equation is

$y = ax^2 + bx + c$

The given quadratic equation is $24x^2 + 2x = 15$

Let's rearrange the equation

$24x^2 + 2x = 15\\24x^2 + 2x - 15 = 0$

This implies that

a = 24
b = 2
c = -15

The equation or formula of quadratic formula is given as

$y = \frac{-b +- \sqrt{b^2 - 4ac} }{2a}$

We can substitute the values into the equation and solve

$y = \frac{-b +- \sqrt{b^2 - 4ac} }{2a}\\y = \frac{-2 +- \sqrt{2^2 -4 * 24 * (-15)} }{2*24} \\y = \frac{-2+-\sqrt{4+1440} }{48} \\y = \frac{-2+-\sqrt{1444} }{48} \\y = \frac{-2+- 38}{48} \\y = \frac{-2+38}{48} \\y = \frac{3}{4}\\ \\or\\y = \frac{-2-38}{48} \\y = \frac{-40}{48} \\y = -\frac{5}{6}$

From the calculations above, the solution to the equation are 3/4 and -5/6 and the greater of the two solutions is 3/4

SOMEONE PLEASE ANSWER ASAP!! 55 POINTS!!

Answer:

EG = 16 and FH =22

Step-by-step explanation:

We know that the diagonals of a parallelogram bisect each other

so 2a = 3b+2

and 2a+3 = 6b-1

We know have a system of equations to solve

2a = 3b+2

2a+3 = 6b-1

Subtract 3 from each side

2a+3-3 = 6b-1-3

2a = 6b -4

Now we can set the 2 equations equal ( 2a = 3b+2 and 2a = 6b -4)

3b+2 = 6b-4

Subtract 3b from each side

3b-3b+2 = 6b-3b-4

2 = 3b-4

Add 4 to each side

2+4 = 3b-4+4

6 = 3b

Divide by 3

6/3 = 3b/3

2 =b

We want to find a

2a = 3b+2

Substitute in b=2

2a = 3(2) + 2

2a = 6+2

2a =8

Divide by 2

2a/2 =8/2

a = 4

Now that we know a and b

EG = 2a + 3b+2

= 2(4) + 3(2)+2

= 8+6+2

= 16

FH = 2a+3 + 6b-1

= 2(4) +3 +6(2)-1

= 8+3+12-1

= 23-1

= 22

Eric is planning to paint the four pillars that are attached to the front of his house. But, he needs to know how many square fe

mariarad [96]

Assume that the pillars are cylindrical..you're looking for the lateral surface area correct? to get the lateral surface area, you use the formula LSA = 2rh(pi) where r is radius h is height substitute the values... h = 10 d = 1 so r =1/2 so LSA = 2 (1/2)(10)(3.14) LSA = 10(3.14) LSA = 31.4 sq ft :D Can You Mark Me Brainlest Plz...
