1 mile = 5280 feet
0.5 mile = 5280/2 = 2640 feet
640 ft is thus smaller than 0.5 miles.
You can write the dimensions of the rectangle as (x + 2) and (x - 5), and because the area is base × height, you can multiply the brackets together and make it equal to 56:
(x + 2)(2x - 5) = 56
2x² + 4x - 5x - 10 = 56
x² - x - 10 = 56
Now because you have an x², you need to make the equation equal to 0 so you can factorise, so:
2x² - x - 10 = 56
- 56
2x² - x - 66 = 0
(x - 6)(2x + 11)
So x is 6, because the other option is -5.5 and you cannot have a negative length.
I hope this helps!
Answer:
columbia- 1
vene-2
brazil- 3
peru- 4
Step-by-step explanation:
So we multiply 2 by 12, and get 24.
Then we multiply 8 by 3, and get 24.
Next we give both terms new denominators -- 3 × 12 = 36.
So now our fractions look like this:
<span><span>24/36</span>−<span>24/36</span></span><span><span>Since our denominators match, we can subtract the numerators.24 − 24 = 0So the answer is:<span>0/36 z</span></span><span>ero divided by anything is just zero. So that's the final answer:
<span>0</span></span></span>
