140-260 and subtract those numbers and that’s the answer
24.99 + 39.99 = 64.98
69.53-64.98 = 4.55
4.55/69.53 = 0.0654 = 6.5% sales tax
Answer:
D.Z
u see how they have line in between as well, shows that they are going by 5 so 2.0 and then 2.5
and if it was asking for -2.5 which is negative two point five, you would choose A.U
There is a theorem in Geometry stating that the square of the tangent segment (ST) is equal to the product of the external secant segment (TR) and the whole secant segment (TQ).
SQ x SQ = TR x TQ
SQ squared = 7 x 30
SQ squared = 210
SQ =
X^2 + 5x = -2
x^2 + 5x + 2 = 0
x = -b (+-) sqrt (b^2 - 4ac) / 2a
a = 1, b = 5, and c = 2
x = -5 (+-) sqrt (5^2 - 4(1)(2)) / 2(1)
x = -5 (+-) sqrt (25 - 8) / 2
x = -5 (+-) sqrt (17) / 2
answer is : negative 5 plus or minus the square root of 17 divided by 2
