Answer:
i really do not know the answer
It says find the product, so that means multiplication
-2[7 -4 0] = [-14 8 0] solving: [-14 8 0] [-3 0 5]
[42+0+70 -24+0+40 0+0+0]
[-14 8 0] * [-3 0 5] = [112 0 -30] = [112 16 0]
[112 16 0]*[6 2 1]
[112 0 -30]* [6 2 1] = [1008 114 0] [672+224+112 96+32+16 +0]
=[1008 114 0].
Answer:
one solution (-3, -6)
Step-by-step explanation:
the two line cross at the point (-3, -6) and only at that one point so there is only one solution (-3, -6).
angles formed by these tosses are 
and 
degrees to the nearest hundredth.
<u>Step-by-step explanation:</u>
Here , We have a triangle with sides of length 8.6 feet, 5.8 feet and 7.5 feet.
The Law of Cosines (also called the Cosine Rule) says:
Using the Cosine Rule to find the measure of the angle opposite the side of length 8.6 feet:
⇒
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
The Law of Sines (or Sine Rule) is very useful for solving triangles:
We can now find another angle using the sine rule:
⇒
⇒
⇒
So, the third angle =
Therefore, angles formed by these tosses are and degrees to the nearest hundredth.
8(x+3)
total means addition and times means multiplication so when you put it together you get 8*x+3 and because you want the total of x*3 you put it in parentheses
