Answer:
width : x+4
Step-by-step explanation:
(x+9)(x+4) = x^2+4x+9x+36
x^2+13x+36
think of numbers that multiply together to get 36
and of those number, what numbers add up to 13
9 times 4 equals 36
9 plus 4 equals 13
1st add 7 to both sides : 3z = 21, 2nd divide both sides with 3: z = 7
8 - 7x - 3 = 19
5 - 7x = 19 |subtract 5 from both sides
-7x = 14 |divide both sides by (-7)
x = -2
Answer:
the answer is a, c and d
a. a=180(n-2)
c. n=a/180+2
d. n= a+360/180
