What is the product of 7.1 * 10^3 and 5.8 * 10^2 expressed in scientific notation?

411.8 ·

Step-by-step explanation:

7.1 · 10³ × 5.8 · 10²

7.1 × 5.8 = 41.18

10³ + 10² =

41.18 ·

Scientific notation can only have one digit after the decimal.

411.8 ·

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

r = 78539458390583095803458309458039485093485 or just 3
