Given:
edge 1 = 3x - 4
edge 2 = x² - 1
edge 3 = 2x² - 15
perimeter if x = 4
edge 1 = 3(4) - 4 = 12 - 4 = 8
edge 2 = 4² - 1 = 16 - 1 = 15
edge 3 = 2(4²) - 15 = 2(16) - 15 = 32 - 15 = 17
Perimeter = 8 + 15 + 17 = 40 feet.
Answer:
slope = 3/2, y-interecept = -.5
Step-by-step explanation:
To find a perpendicular line, just take the current slope (-2/3) and find the opposite reciprocal of 3/2. Then, you can just slowly find your way to the y-intercept through subtraction (or division if you'd rather, both are much quicker than the way most textbooks would tell you - remember, in math, there is no one set way!)
Answer:
2677
Step-by-step explanation:
Let's make this easier first of all:
a^2-y^3(a-y^2)y^2
a^2-y^5(a-y^2)
a^2-ay^5+y^7
(-2)^2-(-2)(3)^5+3^7
4-(-2*243)+2187
4-(-486)+2187
4+486+2187
490+2187
