Answer:

Step-by-step explanation:
x = 180 - 80 - 55 (Interior angles of a triangle add up to 180 degrees so if we need to find any unknown angle, we'll subtract all the other angles from 180)
x = 45 degrees
Answer:
Step-by-step explanation:
in y = mx + b form, the slope will be in the m position and the y int will be in the b position.
y = mx + b
slope(m) = -7/6
y int (b) = -1
y = -7/6x - 1 <== ur equation
Perimeter = length + length + width + width
6 + 6 + 4 + 4 = 20 metres
Answer:
A) 3, B) 8 and 4, C) 12
Step-by-step explanation:
There are 3 terms: 8x^2, 4x, and 12.
The coefficiemts are numbers that come before a variable. That's why the coefficients are 8 and 4.
The constant is the number that doesn't come with a variable, thus 12.
