Answer:
The x-axis.
Step-by-step explanation:
That is the x axis. If you imagine that the x-axis is a mirror you will see why. The corresponding points on the pentagon and its image are the same distance from the x-axis.
Answer:
-12
Step-by-step explanation:
if you use substitution
2*-5+2-4
-10+2-4
-8-4
-12
Answer:
Step-by-step explanation:
The nth term of an AP is expressed as;
Tn = a+(n-1)d
a is the first term
n is the number of terms
d is the common difference
Sixth term
T6 = a+(6-1)d
T6 = a+5d
Third term;
T3 = a+(3-1)d
T3 = a+2d
If the sixth term of an AP is twice the 3rd term, then
a+5d = 2(a+2d)
a+5d = 2a+4d
Given a = 3
3+5d = 2(3)+4d
5d-4d = 6-3
d = 3
Common difference is 3
For the 10th term
T10 = a+9d
T10 = 3+9(3)
T10 = 3+27
T10 = 30
Hence the tenth term is 30
To subtract fractions, let's put a generic example.
Be the fractions
(a / b) - (c / d)
With a, b, c and d other than zero.
The subtraction of fractions is given by:
(a / b) - (c / d) = ((a * d) - (c * b)) / (b * d).
If the fractions have the same denominator then the subtraction is
(a / b) - (c / b) = (a-c) / (b)
answer
(a / b) - (c / d) = ((a * d) - (c * b)) / (b * d)
(a / b) - (c / b) = (a-c) / (b)
Answer:
x^2 + x -12
Step-by-step explanation:
I am going to expand and simplify because you haven't mentioned what to do:
(x-3)(x+4)
x^2 +4x -3x- 12
x^2 +x-12
