3x+y=17
=> 3x=17-y
Again, x+3y=-1
=> 3y= -1-x
now, 3x+3y= (17-y)+(-1-x)
= 17-y-1-x
= 16-x-y
Answer:
the answer is C 36
Step-by-step explanation:
All triangles are 30-60-90, therefore the short legs (2) are half as much as the hypotenuse. Therefore the hypotenuse is 4. Because its a rhombus, all sides are congruent, so you have the length and width and can multiply them to get 16 square units.
Answer:
X = 4
Step-by-step explanation:
And then the nearest tenth would be 0
cause all numbers that have 4 round to like 0 or the tenth under it. If it has a five or higher it rounds to 10 or the number above it
43.786
Since 6 rounds up:
43.79
