Answer:
You must add 9/4 in order to make this a perfect square.
Step-by-step explanation:
To make any binomial into a perfect square trinomial, you have to take the middle term (-3), cut it in half (-3/2) and then square it (9/4). This will give you the constant to make a perfect square trinomial every time.
Answer:
162
Step-by-step explanation:
324/2 because a square has sides that are all equal, so the area is 2 times the length of a side
Answer:
142 3/8 pounds
Step-by-step explanation:
(45 +7/8) + (42 +3/8) + (54 +1/8) = (45 +42 +54) +(7/8 +3/8 +1/8)
= 141 + (8/8 +3/8)
= 142 3/8 . . . . pounds
Answer:
22.6 degrees
Step:
The hypotenuse is 13cm using pythagoras theorem.
Now, finding the smallest angle is by using;
SOH
sin = opposite over hypotenuse
Thus, cos^-1 (12/13)
=22.61
and equals to 22.6 (1d.p）
