8×51 = 8 ×(50+1)=8×50+8×1=400+8=408
Distance ran by Tara = 1600 m
Time taken by Tara to ran 1600 m = 5 min 20 seconds
We have to calculate the speed.
Firstly, we will convert the unit of time in one unit.
Time = 5 min 20 seconds
= 5 min +
min (Because 1 min = 60 sec)
= 
=
=
min
Now we will use Distance speed formula which states,
Distance = speed
time
1600 m = speed

speed = 
Speed = 300 m/min
So, the speed of Tara was 300 meter/min.
Answer:
-5 & 1
Step-by-step explanation:
[x² + 2(x)(2) + 2²] - 2² - 5 = 0
(x+2)² - 4 - 5 = 0
(x+2)² = 9
x+2 = +/- 3
x+2 = 3 x = 1
x+2 = -3 x = -5
Answer:
You have worked cut out for you but have a good day :)!!!!!!!!
Step-by-step explanation:
Answer:
The answer is 4y.
Step-by-step explanation:
First you would solve the parentheses, which would be -1(-3y) which would equal positive 3y, and y+3y=4y. I apologize if I misunderstood the problem ^^
