Answer:
x^2-3x=4
x^2-3x-4=0
x^2-4x+x-4=0
x(x-4)+1(x-4)=0
(x+1)(x-4)=0
x=-1,4
x- intercepts in the point (-1,0) and (4,0)
Step-by-step explanation:
The side which is the opposite of the right angle is the hypotenuse
Answer:
Step-by-step explanation:
Density is defined as mass of an object divided by its volume.
#We calculate the volume of the cylinder:
Given the mass= 15.3kg and volume as above, we calculate density as:
Hence, the solid's density is
Rounding to the nearest 10, we get 660 - 420, which equals 240.
657 - 424 = 233
