Answer:

x=-2/3

Step-by-step explanation:

f(x)=9×2/3x+4

0=9×2/3x+4(substitute f (x) =0)

0=9×2/3x+4

0=3×2x+4

0=6x+4

-6x=4( move the variable to left side and change the sign)

Divide both sides.. x=-2/3

Сorrect statements:
1. EF is the longest side

2. DF = 6 cm (in a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse. )

3. By the Pythagorean theorem:
DE = √(12²-6²) = √(144-36) = √108 = 6√3
DE = 6√3 cm

iragen [17]

Answer:

The total number of cartons did he sale is 20 .

Step-by-step explanation:

Given as :

The total number package in each carton = 28

The total amount received after sale = $ 280

The cost of 10 noodles = $ 5

Let the total number of cartoon sale = x

According to question

∵ The number of noodles costing $5 is 10

so,The number of noodles costing $1 is $\frac{10}{5}$ = 2

∴ The number of noodles costing $280 = 2 × 280 = 560

Now, since there are 28 packages in 1 carton

So . the number of carton did he sale = $\dfrac{\textrm total number of noodles}{\textrm total package in each cartoon}$

Or, The number of carton did he sale = $\frac{560}{28}$ = 20

Hence The total number of cartons did he sale is 20 . Answer
