Which expression has a value greater than 4 raise to 3?

telo118 [61]

We just have to evaluate and compare the numbers:

$4^3 = 64\\(-2)^5 = 32\\(-7)^2=49\\(-3)^4 = 81\\(-5)^2=25$

So, the only expression that exceeds 4^3 is (-3)^4

Mrs. Lovejoy makes flower arrangements. She has 36 red carnations, 60 white carnations, and 72 pink carnations. Each arrangement

Marat540 [252]

Answer:

12 arrangements

Step-by-step explanation:

We solve this question using the Greatest Common Factor method.

We are told that:

She has 36 red carnations, 60 white carnations, and 72 pink carnations.

The same number of each item should be in each basket.

The greatest number of baskets is calculated as follows:

Step 1

The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36

The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

Step 2

We Identify the number that is greatest and common amongst 36,60, and 72

This is 12.

Then the greatest common factor is 12

Therefore, the greatest number of arrangements she can make if she uses every carnation is 12 arrangements

I solve kinda a bit but its hard (Algebra 2)

melisa1 [442]

Answer:

x=9

Step-by-step explanation:

The goal is to combine our knowledge of geometry area and algebra skills to solve this problems.

We know area of rectangle is

$l \times w$

where l is the length and w is the width. We know that one side is 3 less than the other side. We can use L or W but let use L. Let x replace L

One side is x, while the other side is

$x - 3$

Both multiply to 54.

$x(x - 3) = 54$

${x}^{2} - 3x = 54$

${x}^{2} - 3x - 54 = 0$

$(x - 9)(x + 6)$

$x = 9$

$x = - 6$

Distance. is positive so x=9
