Answer:
Length=17
Width=4
Step-by-step explanation:
Length=x
Width=2x-30
x(2x-30)=68
2x²-30x=68
2x²-30x-68=0
2(x²-15x-34)=0
2(x+2)(x-17)=0
So x equals either 17 or -2. Since it can’t be -2, x=17
Length=x=17
Width=2x-30=2*17-30=34-30=4
Answer:
If you expand that, it comes out to 200000000, or in scientific notation, 2.0 × 10⁸.
Step-by-step explanation:
Starting with:
(7 × 10⁵) × (3 × 10²)
Since everything is multiplied, we can drop the brackets:
= 7 × 10⁵ × 3 × 10²
Now we can multiply seven by three, and both powers of ten:
= 20 × 10⁷
We can expand this now as
200000000
or in proper scientific notation:
2.0 × 10⁸
