x - 4/5 > 1/5
+4/5 +4/5 add 4/5 on each sides, 4/5s will cancel on the left side.
__________ solve for 1/5 + 4/5, which is 1.
x > 1, is the final answer.
hope this helps :)
Answer:
The area of ΔABC is 6√6 sq. yards.
Step-by-step explanation:
The area of a triangle using the Heron's formula is:
Here <em>s</em> is given as follows:
The sides of the triangle ABC are as follows:
AB = 6 yd
BC = 7 yd
CA = 5 yd
Compute the value of <em>s</em> as follows:
Compute the area of ΔABC as follows:
Thus, the area of ΔABC is 6√6 sq. yards.
Let X be the width of the path.
The width of the path would be the width of the pool plus 2x, so 2x +16
The length of the path would be the length of the pool plus 2x, so 2x+22
The total area is 832 square feet.
Area is found by multiplying the length by the width.
So you have:
(2x+16) (2x+22) = 832
Use the Foil Method:
(2x+16) (2x+22) = 4x^2 +76x+352
Now you have:
4x^2 +76x+352 = 832
Subtract 832 from both sides:
4x^2 +76x+352-832 = 0
Simplify:
4x^2 +76x -480
Factor the left side:
4(x-5)(x+24) = 0
Divide both sides by 4:
(x-5)(x+24) = 0
Set both parenthesis to equal 0 and solve for x:
x=5 and x = -24
The width of the path cannot be a negative number, so the width is 5 meters.
Answer:
80
Step-by-step explanation:
2 times 10 is 20
8 times 10 is 80
40 times 10 is 400
60 times 10 is 600
