For Answer A, it is 3/4 because there are 4 donuts in total and you have 3 glazed and 1 chocolate, so it will be 3 over 4.
For Answer B, it is 75% because 3 over 4 is 0.75 and if you put it in percentage, then it will be 75%.

Use the quadratic formula to determine the exact solutions to the equation. 6x2+4x−3=0 Enter your answers in the boxes. x = or x

The quadratic formula is x= -b +/- √b²-4ac / 2a

In this problem,

a=6
b=4
c=-3

Now, we can plug this into the formula:

x= -4 +/- √4²-(4)(6)(-3) / (2)(6)
x= -4 +/- √16+72 / 12
x= -4 +/- √88 /12
x= -4 +/- 2√22 /12
x= -2 +/- √22 / 6

So,

x= -2 + √22 / 6
x= -2 - √22 / 6

Are 4(5+x) and (5+4)+x equal

SSSSS [86.1K]

Answer:

No, they are not equal

Step-by-step explanation:

If x = 1

4(5+x) = 4(5+1) = 4 x 6 = 24

(5+4) + x = 9 +1 = 10

24 $\neq$ 10

Help Asap! I have 30 minutes! 30 Points!

Vladimir79 [104]

(2x - 5) (5x - 10)
Use FOIL
10x² - 20x - 25x + 50

10x² - 45x + 50

5( 2x² - 9x + 10)

2x -5
x -2

5(2x - 5)(x -2)

make each equal to 0
2x - 5 = 0
x - 2 = 0

2x - 5 = 0 x - 2 = 0
2x - 5 (+5) = 0 x - 2 (+2) = 0 (+2)
2x = 5 x = 2
x = 5/2

x = 5/2 , 2

hope this helps
