Using the formula sum of interior angles {180(n-2)}
180(15-2)=180
giving you a total of 2340 Degrees
Step-by-step explanation:
62.56
Answer:
a. The possible dimensions of the total area are;
The width of the total area is (2·x + 8) inches
The length of the total area is (2·x + 10) inches
b. The dimensions of the photos are as follows;
The length of the photos are 10 inches
The width of the photos are 8 inches
Step-by-step explanation:
a. Given that the area, A = 4·x² + 36·x + 80
We get;
A = 4 × (x² + 9·x + 20) = 4 × (x + 4) × (x + 5) = (2·x + 8)·(2·x + 10)
Therefore, the possible dimensions of the total area (photo + mat) are;
The width of the total area (photo + mat) = (2·x + 8) in.
The length of the total area (photo + mat) = (2·x + 10) in.
b. The dimensions of the photos alone are shorter than the dimensions of the photo and mat combined by 2·x each
Therefore, we have the dimensions of the photos are as follows;
The length of the photo = (2·x + 10) in. - 2·x in. = 10 in.
The width of the photos = (2·x + 8) in. - 2·x in. = 8 in.
Answer:
D) x^2+2
Step-by-step explanation:
(2x^2+2x+3)-(x^2+2x+1)
2x^2-x^2+2x-2x+3-1
x^2+3-1
x^2+2
A= 35° because 180°-80°-65°= 35°
b=50° because 180°-95°-35°= 50°
c=85° because 180°-95°= 85°
d=30° because 180°-65°-85°= 30°
For these you just have to remember that the sum of the angles of a triangle is 180°, and the same for a straight line.
