Answer:
s = - 1 ± 
Step-by-step explanation:
Given
s² + 2s - 6 = 0 ( add 6 to both sides )
s² + 2s = 6
To complete the square
add ( half the coefficient of the s- term )² to both sides
s² + 2(1)s + 1 = 6 + 1
(s + 1)² = 7 ( take the square root of both sides )
s + 1 = ± ( subtract 1 from both sides )
s = - 1 ±
Thus
s = - 1 - , s = - 1 +
Answer:
5. 6+6i
6. 
Step-by-step explanation:
well, u just need to calculate
Step-by-step explanation:
area of rectangle = l × h
= 9 × y
= 72
9 × y = 72
y = 72÷9
y = 8cm
area of circle = 50.27cm²
total area of the logo = 2(50.27) + 72
= 100.54 + 72
= 172.54cm²
Answer:
x = a(c - b)
General Formulas and Concepts:
<u>Pre-Algebra</u>
Step-by-step explanation:
<u>Step 1: Define Equation</u>
x/a + b = c
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract <em>b</em> on both sides: x/a = c - b
- Multiply <em>a</em> on both sides: x = a(c - b)
Since you answered the first 2 i can go to c and d.
C can really be anything since it's being multiplied by 0 no matter what you put there it will be 0.
But for D it's 1/10^2
Hope this helps ^^
