Answer:
3xy - xz, or x(3y - z)
Step-by-step explanation:
2x(y-z)+x(y+z) becomes
2xy - 2xz)+ xy + xz)
combining the xy terms, we get 3xy;
combining the xz terms, we get -xz
Thus, the complete simplified expression is 3xy - xz, or x(3y - z)
That the result will be negative
because
a negative number, example -2 is equal to -1 times 2
odd power
even powers cancel negatives
so examle
(-2)^3=((2^3)((-1)^3)=(8)(-1)=-8
the concluseion is that the result will be negative
Answer:
C
Step-by-step explanation:
In C, angle 1 and 2 are alternate exterior angles, meaning that they are equivalent. They are only corresponding angles in the other options and corresponding angles are not always congruent. So the answer must be C.
The volume of a rectangular prism is simply length * width * height.
Therefore, all we have to do to find the height of the cereal box is divide the volume by the width and the length.
144 / 8 = 18
18 / 1.5 = 12
The cereal box is 12 inches tall.
Hope that helped =)
