Which expression is equivalent to a + (c + 7)?
Elina [12.6K]

Answer:

(a + c) + 7

Step-by-step explanation:

Because the only type of math in this expression is addition, whatever way you write it (keeping only plus signs), the answer will be the same. So,              a + (c + 7) is equal to (a + c) + 7.

I hope this helps!

The ratio of the lengths of the sides of a triangle ABC is 3:4:6. M, N, and K are the midpoints of the sides. Perimeter of the △
juin [17]

Given that in a trianlgle the sides AB, BC, CA are in the ratio 3:4:6.

Let AB = 3k, BC = 4k and CA = 6k.

Then perimeter =3k+4k+6k = 13k

M, N, K are mid points of the sides.

By mid point theorem MN = 3k/2, NK = 4k/2 and KM = 6k/2

Hence perimeter of MNK = 13k/2 =5.2 (given)

Solve for k

k=2(5.2)/13 = 0.8

Hence sides are

AB = 3k = 3(0.8) = 2.4 in

BC = 4k= 3.2 in

CA = 4.8 in
