Answer:
r = 5
Step-by-step explanation:
(r + 8)^2 = r^2 + 12^2
r^2 + 16r + 64 = r^2 + 144
16r = 80
r = 5
The answer is -60.
Why is this so??
The information we have here is that Rafeal rode his bike downhill by 6 kilometers.
Every kilometer he rides his bike, the altitude declines by 10m (meters)
let <em>m</em> represent how many meters the altitude declined.
If there is a positive number (ex. 2) multiplied by a negative number (-2), The result will be negative (-4) and vice-versa.
Same goes with division. positive number (4) divided by negative number (-2), the result will be a negative quotient.
<em>Therefore, the answer would be -60m, or -60 meters.</em>
Solve: 4(6x - 10) = 8x + 40
A 0
B.5/2
c. 23
D. 5
<h3><u>Answer:</u></h3>
Option D
The solution to given equation is x = 5
<h3><u>Solution:</u></h3>
Given that we have to solve the given equation
4(6x - 10) = 8x + 40
Let us solve the above expression and find value of "x"
Multiplying 4 with terms inside bracket in L.H.S we get,
24x - 40 = 8x + 40
Move the variables to one side and constant terms to other side
24x - 8x = 40 + 40
Combine the like terms,
16x = 80

Thus solution to given equation is x = 5
the answer is 3^5 because multiplication is done by adding the carriers
