based on the drawing both sides are the same length
so knowing BC = 23 you need to find the value of x and put it in the formula for the side
23=2x+7
16 = 2x
x=8
4x+1 = 4(8)+1 = 33 units
Momentum =mass x velocity
therefore
velocity=184 divide by 92 = 2 m/s
If two triangles are similar, then their side lengths are proportional.
RS / JK = RT / JL
5 / x = 4 / 7
4x = 35
x = 35/4 = 8.75
RT / JL = TS / LK
4 / 7 = 6 / (y + 2)
42 = 4(y + 2)
42 = 4y + 4
4y = 38
y = 38/4 = 9.5
LK = 9.5 + 2 = 11.5 cm
JK = x = 8.75
Hope this helps!
Your answer:
<span>Equation:
x(x+1) = 2(x+1)+77
-----
x^2+x = 2x+79
x^2-x-79 = 0
------
This quadratic does not have an integer solution.</span>
36 throws because you divide 60 by five and get 12 and then multiply 3 by 12 giving you 36, are you sure this is high school
