Answer:
233.8 Yards
Step-by-step explanation:
Given that,
Length of a rectangular field, l = 227 yards
Breadth of a rectangular field, l = 56 yards
Let x is the distance from one corner of the field to the opposite corner. It can be calculated using Pythagoras theorem,
So, the distance from one corner of the field to the opposite corner is 233.8 Yards.
In -2^2 since the negative sign is not in parentheses you would solve it as 2×2=4 and then have the negative sign so it would be -4. With the parentheses you are saying that the term you are squaring is (-2) and two negatives make a positive so it would be (-2)×(-2)= 4.
-7x+14y=-14
-3x+7y=-3
when using elimination you need to multiply or divide one equation to be able to “eliminate” a variable.
-7x+14y=-14
-2(-3x+7y=-13)
multiply the second equation by -2
-7x+14y=-14
6x-14y=6
simplify
-1x=-8
divide by -1 on both sides to isolate the x
x=8
now you can plug in 8 for x in one of the equations.
-3(8)+7y=-3
simplify
-24+7y=-3
add -24 to both sides the isolate the constant and variable
7y=21
now divide by 7 on both sides to isolate y
y=3
this system of equation had one solution at (8, 3)
i hope this helps :)
-2x^2-3x is how you can simplify the expression
Answer:
710
Step-by-step explanation:
When you round to the nearest tenth the last number needs to higher or lower then 5 and if its higher it will round up to 710
