Answer:
a) 16
b) 100
c) 64
d) [/tex]
Step-by-step explanation:
Perfect square trinomial:
A perfect square trinomial has the following format:
a.
x² – 8x
So 2a = 8, a = 4. Then
The perfect square trinomial is
b. x2 + 20x +
2a = 20, so a = 10
The perfect square trinomial is
C.
x² – 16x +
2a = -16, so a = -8.
The perfect square trinomial is
d. x2 + 9x +
, so
The perfect square trinomial is [/tex]
Answer:
The first number is 138.
Step-by-step explanation:
Let the first number be <em>x.</em>
<em />
Then since they are consecutive numbers, the second number will be (<em>x</em> + 1), the third (<em>x</em> + 2), the fourth (<em>x</em> + 3) and the fifth being (<em>x</em> + 4).
We are given that their sum is 700. Therefore:
Solve for <em>x</em>. Combine like terms:
Subtract 10 from both sides:
Divide both sides by five. Therefore:
The first number is 138.
