Jamie used the distributive property to find the product of s(t) and h(t). His work was marked incorrect. Identify Jamie's mista
SSSSS [86.1K]

Complete Question:

Jamie used the distributive property to find the product of s(t) and h(t). His work was marked incorrect. Identify Jamie's mistake. What advice would you give Jamie to avoid this mistake in the future?

s(t)•h(t)= (3x-4)(2x-8)

= 6x² - 24x -8x - 32

= 6x² - 32x - 32

Answer:

Jamie made a mistake in his second line (6x² - 24x -8x - 32), by wrongly multiplying the operation signs. The last term should be +32, not -32.

Advice: Jamie should take note of the rule that applies when multiplying signs.

Step-by-step Explanation::

To find out where exactly Jamie made mistake, let's find the product of the given functions, step by step:

s(t)•h(t)= (3x-4)(2x-8)

Using distributive property, do the following:

3x(2x - 8) -4(2x - 8)

3x*2x -3x*8 -4*2x -4*-8

6x^2  - 24x - 8x + 32 (this is where Jamie made mistake. -4 * -8 = +32. NOT -32.)

Add like terms

6x^2  - 32x + 32

Jamie made a mistake in multiplying negative × negative. The last term in "6x² - 24x -8x - 32", should be +32. Negative × negative = +.

Therefore, it is advisable for Jamie to always take note of the rule that applies when multiplying signs.

What are some key ways to solve math word problems? How can you tell which math category does a problem solving question fall in
OlgaM077 [116]

Look for "Math Clues." Math Clues are like how many, fewer, left, and more.

How many is the total.

Fewer & Left are subtraction.

More represents add.

The given expression is: 
(x/2) + 5

Let's look at each terms separately:
x/2 means that you you're getting half the value of a number
+5 means that you are adding 5
Combining both, you can conclude that you are adding 5 to half a certain given number.

Comparing this with the choices, the correct choice would be:
C. five more than half a number.
