Answer:
8.94 m
Step-by-step explanation:
Use the Pythagorean Theorum - 
. Use leg 1 as <em>a</em>, leg 2 as <em>b</em>, and the third side as <em>c</em>.
We know leg 1 is 4, and that leg 2 is twice as long as leg 1...
Now, we use the Order of Operations to find 
...
Now, we find the square root of to find c...
So, the length of the third side is 8.94 m.
Answer:
the area of the parallelogram is 5000cm²
Answer:
(1/2,4)
Step-by-step explanation:
First, determine y in first equation: 2x+y=5 or y=5-2x
replace value of y determined in first equation (5-2x) into 2nd equation
4x-3(5-2x)=-10
4x-15+6x=10
10x=5
x=1/2
put value of x into either equation to solve for y so
2(1/2)+y=5
1+y=5
y=4
answer: x=1/2, y=4
check answer by substituting x and y into either equation:
4x-3y=-10
4(1/2)-3(4)=-10
2-12=-10
-10=-10
or
2x+y=5
2(1/2)+4=5
1+4=5
5=5
