Answer:
-23/4
Step-by-step explanation:
add everything in the ()
your'e left then with -1/2(11/2)-3
then multiply
and get -11/4-3
when you subtract you are left with -23/4
You can use the pythagorean theorem.

Now lets write out what we know.
Shorter leg = x
Longer Leg = x + 7
Hypotenuse = x - 7

Now solve for x

x = 28
Since you know x = 28, which is the shorter leg, you can solve for the rest by just plugging in 28 where x is located. For instance, longer let is x + 7 so
28 + 7 = 35
I like using decimals instead of fractions.
1/8: 0.125
So the scale is:
0.125 in: 1.5 mi
What you do to one side you have to do to the other side. We have the map distance, which is 2.5. Let's see what it was multiplied by to find the map distance of their houses.
2.5÷ 0.125= 20
Let's multiply the other side by 20.
20×1.5
30
So, Juanita and Lindsey live 30 minutes away.
Answer:
(ab-bc)²
Step-by-step explanation:
- ab(ab-bc)+bc(bc-ab) = ⇒ distribution
- (ab)² - ab*bc + (bc)² - ab*bc = ⇒ regrouping
- (ab)² - 2ab*bc + (bc)² = ⇒ applying (x-y)² = x² -2xy +y² formula
- (ab-bc)² ⇒ final result
