Carmine buys 9 plates for $2 each. He also buys 10 bowls. Each bowl costs twice as much as each plate. The store is having a sale that gives Carmine $4 off the total cost of the bowls.
Which numerical expression shows how much he spent?
A
(9 * $2)+((10 $4) - $4]
B
(9 * $2)+(10 ($18 - $4)]
C
(9 * $10) + [(10 $4) - $4]
(9* $2)+((10 x $18) - $4)

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
