The product of one term of a multiplicand and one term of its multiplier
AC = √(40²-12²) = √(1600-144) = √1456 = 4√91
tanA = 12/4√91 = 3/√91 = 3√91/91
option а.
Its -1/2 because they are 9/4 then 7/4 then 5/4 then 3/4 and thats -2/4 which is equal to -1/2
$1351.58 is the correct answer
Answer:
C. 4x
Step-by-step explanation:
x means 1x, so the coefficient is 1.
1x + 1x + 1x + 1x
Ignore the x's for a bit.
1 + 1 + 1 + 1
That gives you 4
Hence 4x (don't forget the variable)
