Please help me answer and explain number 55
melamori03 [73]

Answer:

D

Step-by-step explanation:

An operation of two real numbers is defined by the rule

a\bigotimes b=b^a+2ab

Calculate 2\bigotimes (1\bigotimes 3). First evaluate the expression in brackets:

1\bigotimes 3=1^3+2\cdot 1\cdot 3=1+6=7

Now,

2\bigotimes (1\bigotimes 3)=2\bigotimes 7=2^7+2\cdot 2\cdot 7=128+28=156

Factor the quadratic expression 3x to the 2nd power +9x +6
Naily [24]

Answer:

3(x + 1)(x + 2)

Step-by-step explanation:

Given

3x² + 9x + 6 ← factor out 3 from each term

= 3(x² + 3x + 2) ← factor the quadratic

Consider the factors of the constant term (+ 2) which sum to give the coefficient of the x- term (+ 3)

The factors are + 1 and + 2, since

2 × 1 = 2 and 2 + 1 = 3, thus

x² + 3x + 2 = (x + 1)(x + 2) and

3x² + 9x + 6 = 3(x + 1)(x + 2)

Based on the table given on the punch recipe, the correct answers are:

  • 48 cups.
  • 48 cups.
  • 8
  • 8 cups of frozen strawberry.

<h3>What does the table on the punch recipe show?</h3>

3 gallons of punch in cups is:

= 16 cups per gallon x 3 gallons

= 48 cups

The amount that Chandra should multiply each ingredient by is:

= 48 cups / 6 cups per recipe

= 8

The number of cups of frozen strawberries needed is:

= 8 x 1

= 8 cups
