Solve, using linear combination.

p – q = 8
2p – q = 19

which ordered pair, (p, q), is the solution to the system of equations?

a) (4, –4)

b) (10, 1)

c) (–4, 4)

d)(11, 3)

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

110698.56 square miles

step-by-step explanation:

multiply 3.8 by 102

387.6

multiply 2.8 by 102

285.6

multiply those two to get
