<span>When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:
</span>1) Square all 3 sides.
2) Sum the squares of the 2 shortest sides.
3) Compare this sum to the square of the 3rd side.
if sum > 3rd side² Acute Triangle
if sum = 3rd side² Right Triangle<span>
if sum < 3rd side² Obtuse Triangle
1) 1,296 2,401 3,600
2) Sum = 3,697
3) </span><span>3,697 is greater than 3,600
Therefore, the triangle is acute.

Answer:
Five bottles
Step-by-step explanation:
Answer:
1.Convert all volumes to ounces
(a) Chlorpheniramine
(b) Lidocaine
V = 2 oz
(c) Banana flavouring
2.Calculate the total volume
Chlorpheniramine = 3.38 oz
Lidocaine = 2
Banana flavouring = <u>0.08
</u>
TOTAL = 5.46 oz
3. Calculate the number of bottles
The prescription will fill five bottles. The sixth bottle will be less than half-full.
Answer:
6
Step-by-step explanation:
I'm not sure if you mean whether a = -3, but if you are to plug in -3 for a you should get:
Answer:
b = -10.5, a = 3.5
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
Find the two numbers their sum is -7 and their difference is 14.
a + b = -7
a - b = 14
<u>Step 2: Solve for a in the first equation</u>
a + b - b = -7 - b
a = -7 - b
<u>Step 3: Find the b in the second equation</u>
a - b = 14
(-7 - b) - b = 14
-7 - 2b + 7 = 14 + 7
-2b / -2 = 21 / -2
<em>b = -10.5</em>
<em />
<u>Step 4: Substitute into a</u>
a = -7 - b
a = -7 - (-10.5)
a = -7 + 10.5
<em>a = 3.5</em>
<em />
Answer: b = -10.5, a = 3.5
