Answer:
-8
Step-by-step explanation:
When you factor, you just find two numbers that add to be the first number (16) and multiply to be the second number (64). 8 and 8 both do this. So when we factor, we also add the variable into each equation because it also has been divided into two equations, and we get: (p + 8)(p +8). Notice that the equations are "+8" and not "-8" because two +8s add to give us a +16 and multiply to give us a +64. After that, we just solve the two equations to find the solutions. Subtract 8 from each equation (we do the opposite operation because 8 is positive) to get -8. Because the answer for each equation is the same our answer is -8.
Interest = $250
Principal = $800
Time = 5 years
R = I * 100 / P * T
= 250*100 / 800 * 5
= 25000/4000
= 6.25%
Answer: 21
Step-by-step explanation: 21 because we have to round to the nearest minute, also known as a whole number. 21.333 can be rounded to 21 since 3 is less than 5.
Relation (for left table ) is y=30x
so,
if x= 12, then y must be 12×30= 360
..,................
for the right graph,
relation is y=55x
if x= 12, then y= 12×55= 660
so y must be (660-360)= 300 more ! I guess the answer is 300 !
if you have any doubt, you can comment !
