Answer:
X = 9.5 + m
Step-by-step explanation:
m = money spent
x = money you had at the beginning
x = 9.5 + m
Substitute m in for 3.4
X = 9.5 + 3.4
Solve for x
X = 12.9
You started with $12.90
Answer:
1
Step-by-step explanation:
Tangent of [5 pi]/4
The expression above is given in radian; when ever you have something like this- take note, it's in radian.
Pi [in radian] = 180 in degrees
Hence [5 pi]/4 = [5 x 180]/ 4 =5 x 45 = 225
So Tan 225 = Tan [225-180] =Tan 45
and Tan 45 =1
<span>Trinomial Ax^2 + Bx + C is perfect square if:
A > 0
C > 0
B = ±2√A√C
36b^2 − 24b − 16
C < 0
4a^2 − 10a + 25
2√A√C = 2*2*5 = 20,
B = −10
16x^2 + 24x − 9
not perfect square,
C < 0
4x^2 − 12x + 9
perfect square:
A>0,
C>0,
2√A√C
= 2*2*3
= 12
= -B
= (2x − 3)^2
hope this helps</span>
