Answer:
2 (if the -.25 has an x after it)
If not 1.75
Answer:
153.94 in²
Step-by-step explanation:
The equation for Area is
Area = πr²
Plugging in the value for the radius into r, it will be
(note, r means radius)
Area = π(7)²= 49π ≈ 153.94
The units is -> in² so add that in the end
If you're asking about the largest number that can be written with 3 digits in the given base:
• In base 2, the largest number with 3 digits is
111₂ = 1•2² + 1•2¹ + 1•2⁰ = 7
• In base 12, the largest number with 3 digits is
bbb₁₂ = 11•12² + 11•12¹ + 11•12⁰ = 1727
(in base 12, a₁₂ = 10 and b₁₂ = 11)
The equations that are true for x = -2 and x = 2 are
-4 = 0 and 4
= 16
<h3>What is an equation?</h3>
An equation is a mathematical statement that establishes the equality of two quantities.
Analysis:
Testing the equation x2 - 4 = 0
for x = 2,
- 4 = 4-4 = 0
for x = -2 = (-2)2 - 4 = 4-4 = 0
Therefore x2-4 = 0 is true
Testing for 4x2 =16
for x = 2 , 4(2) ^2 = 4x4 = 16
for x = -2 4(-2)^2 = 4(4) = 16.
All other equations are not true except these two.
