Equilateral triangle ABC has a perimeter of 96 millimeters. A perpendicular bisector is drawn from angle A to side BC at point M
a_sh-v [17]

Answer:

16 mm  

Step-by-step explanation:

Since ABC is an equilateral triangle, all three sides are the same length.  The perimeter is found by adding together all of these equal sides; letting x represent the length of a side of the triangle, this gives us

x + x + x = 96

Combining like terms,

3x = 96

Dividing both sides by 3,

3x/3 = 96/3

x = 32

Since AM is a perpendicular bisector, it splits BC into two congruent sections. This means the length of MC, half of BC, will be 32/2 = 16.

What are the solutions to the equation x^2+6=40?
Andreas93 [3]

Answer:

x = 4  or x = -10   for  equation x^2 + 6x = 40

Step-by-step explanation:

x^2 + 6 = 40

x^2 = 40 - 6

x^2 = 34

x = root(34) or  x = -root(34)   but this is not in the answer choice.

is it  x^2 + 6x = 40

x^2 + 6x + 9 = 40 +9

(x + 3)^2 = 49

x + 3 = 7  or  x + 3 = -7

x = 4  or x = -10
