12-2x^2/-5x where x=-4

10.4

Step-by-step explanation:

to simply solve the expression we will  insert the known value of x into the expression and evaluate.

12-2x^2/-5x

12 - 2x²/-5x given that x = -4

= 12 - 2 (-4)²/ -5(-4)

= 12 - 2(16)/ 20

= 12 -32/20

don't forget to the BODMAS rule

B bracket

O of

Ddivision

M multiplication

A addition

S subtraction

so we have,

12 - 32/20

12 - 8/5

find the lcm

60 - 8/5

52/5

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
