By using scientific notation we calculated (2.3
10⁵)(1.5
10⁴) we got 345
10⁷.
Given that,
(2.3
10⁵)(1.5
10⁴)
By using scientific notation
The scientific notation allows us to express extremely large or extremely small numbers by multiplying them by single-digit integers and by 10 raised to the power of the corresponding exponent. The exponent is either positive or negative depending on how big or little the number is.
Now, we calculate
(2.3
10⁵)=2.5
100000=230000
(1.5
10⁴)=1.5
10000=15000
Now,
=230000
15000
=3450000000
=345
10⁷
Therefore, By using scientific notation we calculated (2.3
10⁵)(1.5
10⁴) we got 345
10⁷.

The trick to calculating the area here is to subdivide the diagram into smaller parts. For example, there's a 3 cm-by-3cm square. The rectangle is 4 cm by 8 cm.. The triangle has a base of 5 cm and a height of 3 cm.
Total area = area of square + area of rectangle + area of triangle
= 9 cm^2 + 32 cm^2 + (1/2)(5 cm)(3 cm)
= (9 + 32 + 7.5) cm^2
= 48.5 cm^2 (total area of figure)
Answer:
48
Step-by-step explanation:
3x^2+12x+15=0
Then divide by 3 to get the x by itself.
x^2+4x+5=0
Factor to (x+5) (x-1) and solve for the two values of x.
