Answer:
KR = 9
Step-by-step explanation:
If K is the midpoint of ER, then EK = KR and ER = 2(EK).
Given:
ER = 2(EK)
⇒ 4x + 2 = 2(x + 5)
⇒ 4x + 2 = 2x + 10
⇒ 2x + 2 = 10
⇒ 2x = 8
⇒ x = 4
As EK = KR and EK = x + 5 and x = 4:
⇒ KR = 4 + 5
⇒ KR = 9
Answer:
y-intercept = 275
x-intercept = 125
Step-by-step explanation:
The y-intercept is the point on your line where x=0. On this line, the y-intercept is the point (0,275) (x,y)
The x-intercept is the point on your line where y=0. On this line, the x-intercept is the point (125,0) (x,y)
Answer:
(x+6)[ 3x-5]
Step-by-step explanation:
3x(x + 6) - 5(6 + x)
We can rewrite the second term in parentheses because order doesn't matter in addition inside the parentheses
3x(x + 6) - 5( x+6)
Factor out the (x+6)
(x+6)[ 3x-5]
Answer:
452.16cm squared
Step-by-step explanation:
Area for a circle formula is A = pi * r^2
Area = 3.14 * 12^2
Area = 452.16
