Answer:
Each pretzel is $4.99
Step-by-step explanation:
20 - 5.03 = 3x
14.97 = 3x
4.99 = x
Answer:
7,11
Step-by-step explanation:
The width is x. x+4= the length. The area is side times side, so it’s
x × (x+4) = 77
We can simplify this to:
x × x + x × 4 = 77
x^2 + 4x = 77
x^2 + 4x - 77 = 0 This is a quadratic equation. So we can solve using the quadratic formula:
x = 
->
That’s the positive solution and that’s x, the width. So the width is 7 and the length is 7+4=11
Answer: x^3 - a^3 = (x - a) (x^2 + ax + a^2) is an identity
Step-by-step explanation:
Verify the identity using trig rules.
Answer:
Kelly is wrong and the recipe will make 19 cups of punch.
Step-by-step explanation:
It says:
The amount of ingredients in the recipe of punch after converting the units to 'cups' are given by,
Pineapple juice = 3 pints = 6 cups (1 pint ≈ 2 cups)
Orange juice = 5 cups
Lemonade = 1/4 gallon = 4 cups (1 gallon = 16 cups)
Apricot nectar = 1 quart = 4 cups(1 quart = 4 cups)
Then, the total cups of punch = 6 + 5 + 4 + 4 = 19 cups.
Thus, Kelly is wrong and the recipe will make 19 cups of punch.
