How to factor completely 2x^2+19x+24

Gnom [1K]

2=2*1,1*2
24=1*24,2*12,6*4,3*8
19=2*8+3

2x²+19x+24
(2x+3)(x+8)

or
2x(x+8)+3(x+8)
2x²+16x+3x+24
2x²+19x+24

Write 30/80 as a percent

Akimi4 [234]

The fraction 30/80 is equivalent to 37.5 percent or 37.5% (rounded to 1 decimal place).

To workout this, divide the numerator by the denominator, sum this value to the integer part then multiply the result by 100%, so:

30/80 in percent = 30 ÷ 80 × 100% =

0.375 × 100% =

37.5%

Do anyone know how to do this?

kykrilka [37]

Answer:

1.) x=4

2.) x=14

Step-by-step explanation:

FOR #1:

1.) In order to solve the parallelogram, you must know that each opposite sides must equal...

so KL=JM and KJ=LM

2.) To solve for "x", you must substitute

$KL= 7x-2\\JM=12x-22$

so it should end up with...

$7x-2=12x-22$

3.) Solve the equation with some algebra

$7x-2=12x-22\\-5x=-20\\x=4$

FOR #2:

1.) In order for a square, rectangle, parallelogram, (or any shape with four sides), it must equal to 360°. And you just have two given angles, which equal to 180, so that means the unknown equals to 180...So in this case you should have

$(3x+5)+(9x-17)+180=360$

as your equation...

2.) Solve with algebra

$(3x+5)+(9x-17)+180=360$

$3x+5+9x-17=180\\12x-12=180\\(\frac{1}{12}) 12x=168 (\frac{1}{12})\\x=14$
