Answer: z= .6
Step-by-step explanation:
Numerator: When you do 5•.6, you get 3, and then 3-1 equals 2.
Denominator: 8 - 3 = 5.
Therefore you get 2/5 which makes z = .6
Answer:
KL = 27
JK = 16
MK = 30
NL = 23
m∠JKL = 132°
m∠KLJ = 22°
m∠KMJ = 54°
m∠KJL = 26°
Step-by-step explanation:
The given parameters of the quadrilateral JKLM are;
JM = 27, ML = 16, JL = 46, NK = 15, KLM = 48, JKM = 78, MJL = 22
Taking the sides as parallel, we have that quadrilateral JKLM is a parallelogram
Therefore;
KL = JM = 27
JK = ML = 16
m∠KLJ = m∠MJL = 22°
MN = NK = 15
MK = MN + NK = 15 + 15 = 30
NL = JL/2 = 46/2 = 23
m∠KJM = m∠KLM = 48°
m∠KJL = m∠KLM - m∠MJL = 48° - 22° = 26°
m∠KML = m∠JKM = 78°
m∠MKL = 180° - m∠KML - m∠KLM = 180° - 78° - 48° = 54°
m∠MKL = 54°
m∠JKL = m∠JKM + m∠MKL = 78° + 54° = 132°
m∠KMJ = m∠MKL = 54°
Answer:
3x²-11x-14=0
Step-by-step explanation:
Given equation is : (3x²+6x+7)-(6x²-5x-7)
Putting the equation equals to zero making it in the form of polynomial equation (3x²+6x+7)-(6x²-5x-7)=0
Opening the bracket of the equation, the negative sign outside the bracket changes the sign of the values after opening the bracket.
3x²+6x+7-6x²+5x+7=0
Solving this by subtracting the values of same type i.e subtracting the component of x having the same power.
3x²-6x²+6x+5x+7+7=0
-3x²+11x+14=0 OR 3x²-11x-14=0
So, on subtracting the above equation the quadratic equation is obtained 3x²-11x-14=0
