Answer:
You can just cancel out on both sides and find the value of the variable.
Step-by-step explanation:
area of quadrilateral = sum of area of triangles
area of triangle ADC = .5 * b * h
= .5 * 12 * 5 = 30 km^2
area of ∆ABC = .5 * sinx* ab* ac
= .5 * sin 30 * 3* 13 = 39/4 = 9.75 km^2
area of quadrilateral = 39.75 km^2
total cost =$ 397.5 million
Answer:
= 2n²
Step-by-step explanation:
From the sequence 2,8,18,32,50
The difference between each numbers are
: 6, 10, 14, 18
The difference between the second sequence is 4.
Therefore the nth term of the sequence is 2n²
Hello from MrBillDoesMath!
Answer:
-15, -14
Discussion:
Let "n" be the first of the two consecutive integers . Per the Question
n + (n+1) = -29 =>
n + n + 1 = -29 =>
2n +1 = -29 =>
2n = -29 -1 =>
2n = -30 =>
n = -15,
Hence n = -15 and n+1 = -15 +1 = -14
Thank you,
MrB
