Answer: x= -2
Step-by-step explanation: use pemdas
10x + 8 = 3(x - 2) distribuite parenthesis
10x + 8 = 3x - 6
10x + 8 = 3x - 6 add like terms
7x +8= -6 add like terms
7x= -14 divide to get x alone
x= -2
Answer:
Step-by-step explanation:
complete the square:
Take a quadratic equation : ax²+bx+c and turn it to
a(x+d)²+e
d=b/2a and e=c-b²/4a
y=x^2 - 14x + 48
a=1 , b=-14 , c=48
d=-14/2=-7
e= 48-14²/4
e= 48-49
e=-1
complete the square for y=x²-14x+48
y= (x-7)²-1
Solution
=14

Answer:
<em>13π/9 rad</em>
Step-by-step explanation:
Given the following
Area of a sector = 26πcm²
radius of the sector = 6cm
Required
central angle measure of the sector in radians
Area of a sector = Ф/2π * πr²
26π = Ф/2π * πr²
26 = Ф(6)²/2π
26 = 36Ф/2π
2π = 36Ф/26
π = 18Ф/26
26π = 18Ф
Ф = 26π/18
<em>Ф = 13π/9 rad</em>
<em>Hence the measure of the central angle in radians is 13π/9 rad</em>
The order from least to greatest is:
E, D, A, B, C
