Answer:
28
Step-by-step explanation:
If you split the shape in half you get a cube and a trapezium, calculate the area of each and add them together to get the area of the entire shape.
When a number has a negative exponent, that means it's on the wrong side of the fraction bar. So since it is 3^-1 , it is equivalent to 1/3.
So 1/3 is 0.333
And 1/4 is 0.25
1/3 > 1/4

Answer: 4/18
Step-by-step explanation:
Answer: one solution x + 3 = 5 x = 2 no other other value for x is possible
No solution: (x + 3) = 2(x +3)
Infinitely many solutions: x+3 = 3 + x
Step-by-step explanation:
why (x + 3) = 2(x +3) has no solution. Can you solve?
x+3=2x+6 -x=3 x=-3 substute -3 for x
(-3)+ 3)= 2[(-3) +3]
-3+3 = -6 +3
0 = -3 False!
x+3 = 3 + x has infinitely many solutions. Substitute any number for x, and the equation is true (5)+3=3+(5) 8=8 . 11111+3 =3+11111 11114=11114
