What is the x in this equation 14x−8=4

Aleksandr-060686 [28]

Answer:

x = 6 / 7

Step-by-step explanation:

Let's solve your equation step-by-step.

14 x − 8 = 4

Step 1: Add 8 to both sides.

14x − 8 + 8 = 4 + 8

14x = 12

Step 2: Divide both sides by 14.

14 x / 14 = 12 / 14

x = 6 / 7

If both the zeroes of a polynomial x2+4x+2p are real and equal then find the value of p.

creativ13 [48]

Answer:

p = 2

Step-by-step explanation:

If both zeroes at equal, they must be the negative half of the second term. As this term is 4, $-\frac{4}{2} =-2$ . This means that each of the zeroes must be -2. This means that the polynomial must be $(x+2)^2$

This simplifies to $x^2+4x+4$

From the intial problem, we can set up an equation and solve for p. $2p=4\\\\p=2$

18 points were scored by one figure skating pair and that was 40% of their final score. What was the final score for that pair o

Phoenix [80]

18 points scored for a pair was 40 % of the final score
then final score is 100%
therefore if 40 % accounts for 18 points
100 % = 18 / 40% *100%
= 45 points is the final score
if we back calculate = 18 /45 *100 = 40%
Therefore the final score is 45 points
