The answer is A = 2x² + 6x - 20
The area of the rectangle is:
A = l * w
l = x + 5
w = 2x - 4
A = (x + 5)(2x - 4)
Use the distributive property to calculate this:
A = (x + 5)(2x - 4)
A = x * 2x + x * (-4) + 5 * 2x + 5 * (-4)
A = 2x² - 4x + 10x - 20
A = 2x² + 6x - 20
Answer:
-1
Step-by-step explanation:
Since 34 is an even number, we can factor a 2 out of the exponent of your problem, like this:
i34=(i2)17.
But, i2=-1, so your problem becomes:
-117.
This means, multiply -1 by itself 17 times, to get -1
(Remember, -1 raised to an odd power is always -1, so -117=-1.)
The final answer is:
i34=-1
Answer:
John has $21.
Step-by-step explanation:
Let John's "wealth" be w. Then 2w+8 = 50, or 2w = 42, or w = 21.
John has $21. Eight more than twice this is 42+8 = 50, as expected.

Step-by-step explanation:
Explicit Arithmetic Formula: 
a₁ is 1st term in sequence
<em>d</em> is common difference
<em>n</em> is term number
Step 1: Find <em>d</em>
d = 8 - 2 = 6
Step 2: Plug in variables into formula
