All the terms are like terms. When combined, their sum is zero (0).
Answer:
Substitute your answer for Step 1 into the second equation to solve for Z.
Since the first number sign is a negative its A
Answer:
5 cm
Step-by-step explanation:
The volume (V) of a cuboid is calculated as
V = lbh ( l is length, b is breadth and h is height )
Here l = 20, h = 12, V = 1200 and b is to be found, thus
20 × b × 12 = 1200, that is
240b = 1200 ( divide both sides by 240 )
b = 5
Complementary: When two angles add up to 90 degrees
Supplementary: When two angles add up to 180 degrees
Similarities are both involve two angles, the difference is the total degrees they add up to.
