<em><u>Answer is 5, 6, & 7</u></em>
x = smallest number
y = x + 1
z = x + 2
(x)(y) = z^2 - 19
(x)(x+1) = (x + 2)^2 - 19
(x^2 + x) = (x^2 + 4x + 4) - 19
x^2 + x = x^2 + 4x + 4 - 19
x^2 term drops out from both sides
x = 4x + -15
15 = 4x - x
15 = 3x
15/3 = x
x = 5
y = x + 1 = 6
z = x + 2 = 7
Confirm by substituting back in for the variables:
(x)(y) = z^2 - 19
(5)(6) = (7)^2 - 19
30 = 49 - 19
30 = 30 <em><u>[OK]</u></em>
Answer:
PR, PW, RW
Step-by-step explanation:
The sides of a triangle are named by naming the vertices at either end.
Triangle PWR has vertices P, W, R. The sides connecting these are named ...
PW, WR, RP
Any name can have the letters reversed. That is, PR names the same segment that RP does.
Answer:
-2, 3
Step-by-step explanation:
That would mean that the other side (the y axis splitting it) would be the same numbers but different signs. The figure's vertex (2,3) is from the 1 quadrant and the one across the y axis is (-2,3) which is in the second quadrant.
hope this helps!!
Answer: Hope this helps if this is what you want.
$14.25
Step-by-step explanation:
$1.50 = 1 ticket
1.50 * 10 = 15
$15 = 10 tickets
100% - 5% = 95% (0.95)
15 * 0.95 = 14.25
$14.25
21X+7=2...........`\21X=2-7...........\ 21X=-5.............. X=-5÷21... this is the right answer..(x=-5÷21)
