Answer:
1.234 + 4.312 + 2.143 + 3.456
= 5.555 + 2.143 + 3.456
= 7.698 + 3.456
= 11.154
Hello from MrBillDoesMath!
Answer:
x = 4
x = ( -7 + sqrt(29)) /2
x = ( -7 - sqrt(29)) /2
Discussion:
x^3+3x^2-23x-20 factors as (x - 4) (x^2 + 7 x + 5) so x =4 is one root
The roots of the quadratic factor, x^2 + 7x + 5, can be found using the quadratic formula where a = 1, b = 7, and c = 5
x = ( -b +\- sqrt(b^2-4ac)) / 2a
x = ( -7 +\- sqrt( 7^2 - 4*1*5) ) / (2*1) =>
x = ( -7 +\- sqrt (49-20) ) / 2 =>
The "+" root: ( -7 + sqrt(29)) /2
The "-" root: ( -7 - sqrt(29)) /2

Answer:
d)1.08421 x 10^25 Kg
Step-by-step explanation:
The combined weight of these two bodies would be the addition of the masses of the two bodies.
Given that Earth weight is 5.9736 x 10^24 Kg and Venus is 4.8685 x 10^24 Kg,
The combined weight of Earth and Venus
= 5.9736 x 10^24 Kg + 4.8685 x 10^24 Kg
=10^24(5.9736 + 4.8685)
= 10.8421 × 10^24 Kg
In standard form,
= 1.08421 × 10^25 Kg
First, we are going to want to see if there are any terms we can simplify. By examining the numerators and denominators of our functions, we can see that we can remove a 3 from the denominator of the second function and the numerator of the first function. This would be represented as:
Now, we can multiply the fractions. Remember that to multiply fractions, simply multiply both the numerators over both the denominators, as shown below:
By applying this information, we can solve for the product of the fractions:
Our answer is 
.
