Find two positive consecutive odd integers such that square of the smaller integer is 10 more than the larger integer

Otrada [13]

Let $2n+1$ be the smaller integer. The larger integer is then $2n+3$ , and we have

$(2n+1)^2=10+(2n+3)\implies4n^2+4n+1=2n+13$

$\implies4n^2+2n-12=0$

$\implies2n^2+n-6=0$

$\implies(2n-3)(n+2)=0$

$\implies 2n-3=0\text{ or }n+2=0$

$\implies n=\dfrac32\text{ or }n=-2$

We omit $n=-2$ , since $2(-2)+1=-3$ is negative.

Then for $n=\dfrac32$ we find $2\left(\dfrac32\right)+1=4$ , but this is not odd.

There are no consecutive odd integers that satisfy the given condition!

What type of triangle, if any can be formed with angle measurements of 32 degrees,126 degrees, and 32 degrees?

lubasha [3.4K]

There can’t be one formed because all sides of a triangle add up to 180 but when you add that it adds to 190 there for it will not make a triangle

An airplane leaves Los Angeles and travels five hours to New YorkCity. The return trip travels along the same route and takes si

finlep [7]

The distance of the plane flies between the two cities is 1,113.75 miles

The formula for calculating the distance travelled is expressed as:

D = vt where:

v is the speed

t is the time taken

Given the following:

v = 99mi/hr

Total time taken = 5hr + 6.25hr

Total time taken = 11.25hr

Get the required distance

Distance = 99mi/hr * 11.25hr

Distance = 1,113.75miles

Hence the distance of the plane flies between the two cities is 1,113.75 miles

Cheryl wants to have $2300 in spending money to take on a trip to Disney World in three years. How much must she deposit now in

Savatey [412]

Use the compound amount formula:

$2,300 = P(1+0.02)^3. Solve this for P:

P = $2,300 / (1.02)^3 = $2167.34.

By depositing $2,167.34 now, Cheryl would have $$2300 after three years.
