Answer:
first option is the correct answer
Step-by-step explanation:
v + w = (-9+1,2-6)
= (-8,-4)
Since both of the equations equal Y can substitute one for the Y and say that
X-1=3x+3
-4=2x
-2=x
Answer:
705
Step-by-step explanation:
141 words in 2 minutes means 70.5 words in a minute
70.5 × 10 = 705 words in 10 minutes
Answer:
192 ft^2
Step-by-step explanation:
to find the surface area of a shape, you must find the area of each side and add them together. the base of this shape is a rectangle with a length of 11ft and a height of 3ft; to calculate the area of a rectangle, you multiply the length by the height. 3*11 is 33, so the base of this prism has an area of 33ft^2. since this is a prism, we know that the side parallel to the base are the same shape, so they both have an area of 33ft^2. 33*2= 66. the two other large sides have a height of 4.5 and a length of 11; 4.5*11 is 49.5, there are two shapes with these dimensions, so 49.5*2=99. finally, the two shapes on either end of the prism have a height of 4.5 and a length of 3. 4.5*3= an area of 13.5, two of them, so 13.5*2=27. now you just add all of these numbers together: 66+99+27=192.
