The first one is 4*8*6=192. 4*10*3=120. 192+120=312. the answer is 312.
the second one is 9x+24. you do this by multiplying the 3 by the parenthesis and then the 2 by its parenthesis then combine variables.
Test the value (x,y) of each point in the equation-y^2 + x <= -4 BY
1) because the equation has = so every point in the equation -y^2 + x = -4 is applied .... this case is B ... satisfy 2) A, E is in the same area choose one to test test A(-4,2) : -(2)^2 + (-4) <= -4 which is true the A and E is satisfy the inequality 3) no need to test fo C, D, F on the different area they are not satisfy. but you can guess it will satisfy -y^2 + x > -4
Option b) and c) is correct, i.e. 2/3 and 0.66(line over 66)7
6/9 is a rational number.
similar ration number can be given as -
<h3>What is rational number?</h3>
Rational numbers are the numbers that can be structured in the form of the fraction of integers. Eg- 5/6, 2/3 etc.
From the option, by above definition 2/3, 0.66(line over 66)7 seems to be an equivalent rational numbers because
6/9=2/3= 0.66(line over 66)7.
Thus, Rational numbers 2/3, 0.66(line over 66)7 are equivalent to 6/9.

Answer:
6⁴ there i hope this helps dude
Step-by-step explanation:
A-- (x)(.10)= New cost
B--New cost-2000= Cost after 10% discount and 2,000 discount
C--You'll have find what number mulitiplied by(.10) equals $18,000
D-- $18,000 is the price with the $2,000 already taken out, so now you just do 18,000(.10)=
