Find the real solutions of the equation
•will mark brainliest•

x = ± 1.68

Step-by-step explanation:

7x^4 = 56

x^4 = 56/7

x^4 = 8

Let a = x²

(x²)² = 8

(a)² = 8

a = ± √8

Now,

a = -√8

x² = -√8 has no real solution.

Taking +√8

a = √8

x² = √8

x = ± √(√8))

x = ± 1.68

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

question: does she have enough ice cream for her guests?

answer: no. explanation: she only has enough for 16 people to have a full serving. however, she can give a 17th person a partial serving.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
