The answer should be X = Z / 6piy
Answer:
One edge of the cube is 5 cm, one edge of the square is 8 cm, so the edge of the cube is 3 cm shorter than the edge of the square.
Step-by-step explanation:
<h3 /><h3>The volume of the cube is found by the formula </h3><h2>V = s³, </h2><h3>where s is the side length (called the edge in this problem)</h3><h3>Since V = 125 cm³, we can take the cube root of 125 to find the edge length.</h3><h3>The cube root of 125 is 5, ( 5³ = 125)</h3><h3>So the edge of the cube is 5 cm</h3><h3 /><h3>The are of a square is found by the formula </h3><h2>A = s² , </h2><h3>where s is the side length (called the edge in this problem) </h3><h3>Since A = 64 cm², we can take the square root of 64 to find the edge length.</h3><h3>The square root of 64 is 8 (8² = 84)</h3><h3>So the edge of the square is 8cm</h3><h3 /><h3>Comparing the two edges tells us that the edge of the cube is 3cm shorter than the edge of the square.</h3>
Answer:
The two consecutive positive integers are 7 and 8
Step-by-step explanation:
Let
x ----> the first positive integer
x+1 ----> the second consecutive positive integer
we know that
Solve for x
Solve the quadratic equation by graphing
The solution is x=7
see the attached figure
Find the value of x+1
x+1=7+1=8
therefore
The two consecutive positive integers are 7 and 8
Answer:
Since that is a quadratic equation, it will have 2 "x" intercepts.
x^2+7x+2
a = 1 b = 7 c = 2
You would solve for "x" using the quadratic formula.
x = [ -b +- sq root (b ^ 2 - 4 a c) ] / 2 a
x = [ -7 +- sq root (7^2 - 4*1*2) ] / 2 * 1
x = [ -7 +- sq root (49 -8) ] / 2
x1 = [-7 + 6.4031242] / 2
x1 = -.29844
x2 = [-7 - 6.4031242] / 2
x2 = -6.7016
