If you need to siplify that radical, you should try to put all the numbers as product of prime factors.

922 = 2*461

2 and 461 are prime numbers. Then the transformation of the square root is √(922) = √(2*461) = (√2)(√461)

So you can use that in any expression to try to simpliy with other numbers whose prime factors include 2 and 461.

Solve 3x²-x-2=0. Please show all work.

3x²-x-2=0

Δ=1+24=25 (Δ=b²-4ac)

x₁,₂= $\frac{1(+/-)\sqrt{25} }{6}$

x₁,₂= $\frac{1(+/-)5}{6}$

x1= $\frac{1+5}{6}$ =6/6=1

x2= $\frac{1-5}{6}$ = $\frac{-2}{3}$

so

x1=1

x2= $\frac{-2}{3}$

write the possible range of the measurement 214 ounces +1.2% round to the nearest hundredth if necessary

boyakko [2]

9514 1404 393

Answer:

[211.43,216.57]

Step-by-step explanation:

1.2% of 214 is ...

0.012 × 214 = 2.568 ≈ 2.57 . . . . rounded to hundredths

Then the minimum possible value is ...

214 -2.57 = 211.43

and the maximum possible value is ...

214 +2.57 = 216.57

The range is 211.43 to 216.57.

Find the area of a square with a side measure of 3x − 6 feet. Question 5 options: 9x2−36x+36 sq. ft. 9x2−6 sq. ft. 9x2+36x+36 sq

Sergeeva-Olga [200]

Answer:

9x^2 - 36x + 36 sq. ft. (the first option).

Step-by-step explanation:

Area of a square of side d = d^2.

So area of this square = (3x - 6)^2

= (3x - 6)(3x - 6)

= 3x(3x - 6) - 6(3x - 6)

= 9x^2 - 18x - 18x + 36

= 9x^2 - 36x + 36 sq ft.
