The single line marks indicate the two lines have the same length. Thus, the unknown length is 3 cm. 15 mm = 1.5 cm, 25 mm = 2.5 cm. The rest is trivial.
Remember to make the polynomials to equal zero, one or the other polynomial must equal zero. So...
2x-3 = 0
2x= 3
x=3/2
and
4x+5 = 0
4x = -5
x = -5/4
So the answers are x=3/2 and x = -5/4
Hope this helps!
Answer:
1/9
Step-by-step explanation:
If the two players choose randomly, there are 3×3 = 9 possible outcomes. Of those, only one is "Bobby chooses paper and wins."
The probability of that event is 1/9.
The answer to this is 8.
You can solve this by divide 64 into 8.
64/8=8
z=8
Step-by-step explanation:
Look at the picture.
If 180° < θ < 360°, then θ is in QIII or QIV. Therefore:
In QIII positive values has tangent and cotangent.
In QIV, positive values has cosine.
