Answer:
The answer is option 3.
Step-by-step explanation:
Option 3 is correct because it has parentheses around 40 - x, but not the cube itself or the 3rd power if you didn't know what I meant. Anyway, the reason this is correct is because if you look at any order of operations, you will notice that parentheses always comes before powered numbers, so if you were to choose, say option 2, it would be a completely different answer than option 3, not to mention wrong also.
Answer:
x = 3 and x = 7
Step-by-step explanation:
Equate the product of the factors to zero, that is
(x - 3)(x - 7) = 0
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 7 = 0 ⇒ x = 7
Answer:
1/4(x+2) = 3
Step-by-step explanation:
Let's do this one thing at a time.
1/4 of a number means 1/4 times a number. We'll use x to represent "a number," so we have
1/4x
But wait: we need to add 2 to a number (sum = addition). So we have
1/4(x+2)
This is three, so we know that expression is all equal to 3.
1/4(x+2) = 3
