Answer:
C.) n < 6
Step-by-step explanation:
Subtract 8:
n/-3 > -2
Multiply by -3. The negative multiplier requires the comparison be reversed:
n < 6
Answer:
x +3 = x^2 +2x -4
Step-by-step explanation:
Straight substitution of the top expression for y gives you ...
x +3 = x^2 +2x -4
__
This lets you rewrite the equation to standard form as ...
x^2 +x -7 = 0
and find the solutions to be ...
x = (-1±√29)/2
Corresponding y-values will be 3 more than this:
y = (5±√29)/2
Use Pythagorean theorem here.
Walkway is √40²+30² so 50
Answer:
80 ft²
Step-by-step explanation:
A (rectangle) = 2*16 = 32 ft²
Length of pink line is x² = 10² - 8², x =√36 = 6 ft
A(triangle) = (1/2)*base*height = (1/2)*8*6=24 ft²
Area of two triangles = 2*24 = 48 ft²
All area = area of rectangle + area of two triangles = 32 + 48 = 80 ft²
Answer:
Hey there!
These triangles can be proved congruent by the HL Theorem.
Hope this helps :)
