The distance between city a and city b is 22 miles. the distance between city b and city c is 54 miles. the distance between city a and city c is 51 miles.

what type of triangle is created by the three cities?

an acute triangle, because 222 + 542 > 512

an acute triangle, because 222 + 512 > 542

an obtuse triangle, because 222 + 542 > 512

an obtuse triangle, because 222 + 512 > 542

The correct answer is:

B. An acute triangle, because .

An acute triangle is created by the three cities.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

i think the answer is d im not sure
