3 0

Answer:

A

Step-by-step explanation:

3x^2 - 8x + 4 = 0

x= [-b +or- square root (b^2 - 4ac)] ÷ 2a

= [-(-8) +or- square root (-8)^2 - 4(3)(4)] ÷ 2(3)

= [8 +or- square root 16] ÷ 6

= 2 or 2/3

Simplify expression with rational exponents.
musickatia [10]
27^(4/3)+4^(3/2) can be simplified using roots.  

The cube root of 27 is 3 and the square root of 4 is 2.  This removes the denominators from the expression.  The expression is now 3^4+2^3.

Simplify this and you get 81+8=89

What is the solution to -55+q=7<br><br> A. a=-62<br><br> B. q=62<br><br> C. q=42<br><br> D. q=-42
Scorpion4ik [409]

Answer:

C, as q = 62.

Step-by-step explanation:

When you have an equation, your goal is to get the letter you are solving for alone. To do this, you employ a simple rule: what you do to one side of the equals sign, you must do the other.

To isolate q in -55 + q = 7, you must add 55 to the left side. q is now alone. However, because we added 55 to the left side, we must also do it to the right! 7 + 55 = 62, so the new right side is 62. Hence, we get to this:

q = 62

The answer is now in plain sight!
