Answer:
B
Step-by-step explanation:
If A = {1, 2, 3} and B = {1, 2, 3, 4, 5}
We say that A is a subset of B, since every element of A is also in B.
So
If set A is all odd numbers then R belongs to A bcz all the elements of R are odd numbers
The surface area (SA) of a rectangular prism (box) is obtained by the equation,
SA = 2 (LW + WH + LH)
where L is length, W is width, and H is height.
Substituting the values for the dimensions,
SA = 2 (15cm x 22cm + 22cm x 9cm + 15cm x 9 cm) = 1326 cm²
Thus, the surface area of the box is 1326 cm².
Answer:
Step-by-step explanation:
Let's solve your system by substitution.
2x+3y=15;x+y=6
Rewrite equations:
x+y=6;2x+3y=15
Step: Solvex+y=6for x:
x+y=6
x+y+−y=6+−y(Add -y to both sides)
x=−y+6
Step: Substitute−y+6forxin2x+3y=15:
2x+3y=15
2(−y+6)+3y=15
y+12=15(Simplify both sides of the equation)
y+12+−12=15+−12(Add -12 to both sides)
y=3
Step: Substitute3foryinx=−y+6:
x=−y+6
x=−3+6
x=3(Simplify both sides of the equation)
Answer:
x=3 and y=3
