Answer:
true
Step-by-step explanation:
A=.5(h)(b)
A=.5(8)(14
A=4(14)
A=56 cm^2
Twice 2 to the 30-th power is
2*2³⁰ = 2¹*2³⁰ = 2³¹
For very large numbers, it is the usual practice to use scientific notation.
From the calculator, obtain
2³¹ = 2.1475 x 10⁹
Answer: 2.1475 x 10⁹
Answer: x = 7
Step-by-step explanation:
4(2x-3) = 6x+2 <--distribute the 4
8x - 12 = 6x + 2 <---add 12 to both sides
8x = 6x + 14 <--- subrtract 6x from both sides
2x = 14 <--- divide by two
x = 7
To get rid of a cube root, we must cube:
(x+8) = -64
Subtract 8:
x = -72
