Answer:
Angle 1 = 70, Angle 2 = 90, Angle 3 = 70, Angle 4 = 70
Step-by-step explanation:
1. 90 -20 = 70
2. Diagonals are perpendicular and create right angles that equal 90
3 and 4. Diagonals bisect angles, angles on opposite sides are congruent
I'm guessing you mean a^2? if so then,
a^2+28a+27=
(a+1)(a+27)
Answer:
4 movies, $20
Step-by-step explanation:
Given data
Family Video
charges $10 for a monthly membership and
$2.50 per movie
let the number of movies be x
and the charge for x movies be y
y= 10+2.5x----------1
Babe's Movies
charges a $12
membership and $2 per
movie.
let the number of movies be x
and the charge for x movies be y
y= 12+2x----------2
equate 1 and 2
10+2.5x= 12+2x
collect like terms
12-10= 2.5x-2x
2= 0.5x
x= 2/0.5
x= 4 movies
put x= 4 in equation 1 or 2
y= 12+2x----------2
y= 12+2*4
y= 12+8
y= $20
Answer:
0
Step-by-step explanation:
