We can calculated the equivalent expression for every option:
For
Answer:
-a^2 +ab +3a
Step-by-step explanation:
-a(a-b-3)
Distribute
-a*a -a*(-b) -a *(-3)
-a^2 +ab +3a
<h3>FALSE</h3>
if r < 0, then is alternating
if 0 < r < 1, then is decreases
if r = 1, then is constant
if r > 1, then is icreases
X = 35
Step 1: Multiply both sides of the equation by seven thirds
Step 2: Reduce sides
Step 3: Multiply the numbers
Answer:
Draw a picture and you'll see a right triangle with sides = 7 and 24 and hypotenuse = r (the cricle's radius). By the Pythagorean Theorem:
r2 = 72 + 242
Area = pi·r2
Step-by-step explanation:
