Answer:

- 1 5/24 cm

Step-by-step explanation:

We'll have to get the fractions to a common denominator. the least common denominator for 3 and 80 is 240.

So - 1 1/3 = - 1 80/240 = 320/240

21/80 = 63/240

-11/80 = -33/240

-------------------------------------

-320/240 + 63/240 - 33/240 = -290/240 = - 1 50/240 = -1 5/24 cm

Expand the expression and combine like terms:-4(-11+4n)-3(-2n+9)
Blizzard [7]
Easy,

split them up,

-4(-11+4n)=

=44-16n

then

-3(-2n+9)=

=6n-27

Making it, 44-16n+6n-27, add your apples and oranges

-16n+6n=-10n

44-27=17

-10n+17.

Thus, this is your answer.

BCD is a straight line.
Ksenya-84 [330]
It’s an isosceles triangle because angle A is equal to angle C (63deg). This is calculated by 180 - 117 = 63 degrees.
Using the exterior angle is equal to the interior angles property, angle A is equal to 117 - 54 (which is 63).
Because these two angles are equal to eachother, the triangle is isosceles.
