Find the value of x on this triangle

Mathematics
1 answer:
Vadim26 [7]3 years ago
4 0

Answer:

x = 35

Step-by-step explanation:

We can use the Pythagorean theorem since this is a right triangle

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

x^2 + 12^2 = (x+2)^2

FOIL

x^2+144=x^2+4x+4

Subtract x^2 from each side

144= 4x+4

Subtract 4 from each side

140 = 4x

Divide by 4

35 =x

romanna [79]

Answer:

859

Step-by-step explanation:

The demand for Coke products varies inversely as the price of Cole products.

Mathematically:

D α 1/p

Where D = demand, p = price of coke product

D = k/p

Where k = constant of proportionality.

Let us find k.

k = D * p

When Demand, D, is 1250, price, p, is $2.75:

=> k = 1250 * 2.75

k = $3437.5

Now, when price, p, is $4, the demand will be:

D = 3437.5/4

D = 859.375 = 859 (rounding to whole number)

The demand for the product is 859 when the price is $4.
