Glenn bought 3 pounds of tomatoes. He used 5/8 of them to make sauce.
n200080 [17]

<em>Question Continuation:</em>

<em>Glenn bought 3 pounds of tomatoes. He used 5/8 of them to make sauce. </em>

<em>Make an equation that shows the number of pounds of tomatoes Glenn used for the sauce.</em>

<em></em>

Answer:

y = \frac{15}{8}\ lb

Step-by-step explanation:

Given

Weight of Tomato = 3 lb

Used Proportion = 5/8

Required

Determine the portion used

To solve this we simply multiply the used proportion by the weight of the tomato bought

Represent the used portion with y.

So:

y = Weight * Used\ Proportion

y = 3\ lb * \frac{5}{8}

y = \frac{15}{8}\ lb

Prove that (n+5)^2-(n+3)^2 is a multiple of 4 for all positive integer values of n
hodyreva [135]

Answer:

Proved

Step-by-step explanation:

Given

(n+5)^2-(n+3)^2

Required

Show that (n+5)^2-(n+3)^2 is a multiple of 4

Expand each bracket

(n+5)(n+5)-(n+3)(n+3)

Open brackets

n^2 + 5x + 5x + 25 - (n^2 + 3x + 3x + 9)

n^2 + 10x + 25 - (n^2 + 6x + 9)

Open bracket

n^2 + 10x + 25 - n^2 - 6x - 9

Collect Like Terms

- n^2 + n^2 - 6n + 10n + 25  - 9

- 6n + 10n + 25  - 9

4n + 25  - 9

4n + 16

Factorize

4(n + 4)

Hence, the multiples of (n+5)^2-(n+3)^2 are 4 and (n + 4)
