Answer:

x^2+3x+5 miles.

Step-by-step explanation:

We have been given that Joy is training for a triathlon. She runs a distance of 2x  miles, cycles a distance of (x^2+7) miles, and swims a distance of (x-2) miles. We are asked to find total distance covered by Joy.

\text{Total distance}=\text{Distance covered by running}+\text{Distance covered by cycling}+\text{Distance covered by swimming}

\text{Total distance}=(2x)+(x^2+7)+(x-2)

\text{Total distance}=2x+x^2+7+x-2

\text{Total distance}=x^2+2x+x+7-2

\text{Total distance}=x^2+3x+5

Therefore, Joy covered a total distance of x^2+3x+5 miles.

At what point does a line with a slope of 34 and a y-intercept of -5 intersect a line with a slope of −14 and a y-intercept of 3
maw [93]
Set them into slope-intercept forms of equations then set those equations equal to each other and solve for x and y.  y = 34x - 5 and y = -14x+3.  Set those equal to each other, solve for x to get x = 1/6.  Sub in that x value to get y = 2/3.  The point where they intersect is the solution of the system; in other words, where on both lines we have the exact same (x, y) value.

The expression n2 + n represents the total number of blocks used in the nth figure of a pattern. Use the equation n2 + n = 56 to
Brrunno [24]

We have to solve this quadratic equation n^{2}+n=56 for n to get <em>which figure has 56 blocks</em>.

n^{2}+n=56\\n^{2}+n-56=0

For middle term factorization, we need <em>two numbers that multiplied gives us -56 and added gives us 1 (coefficient of n).</em>

<em>Such two numbers are </em><em>8</em><em> and </em><em>-7</em><em>. We can now write,</em>

<em>n^{2}+n-56=0\\(n+8)(n-7)=0\\n=-8, 7</em>

<u><em>"There is no negative figure number possible, so we disregard -8"</em></u>

Our answer is 7.


ANSWER: The 7th figure has 56 blocks.
