Z²(z-1)-9(z-1)
= (z²-9)(z-1)
= (z+3)(z-3)(z-1)
Just did this one.
The perimeter is the sum of the sides.
n + (3n - 4) + (3n - 5) = 33
7n - 9 = 33
7n = 42
n = 6
3n-4=18-4=14
3n-5=13
Check: 6+14+13=33, good
Answer: 6 cm, 14 cm, 13 cm
PEMDAS is the order of operations....it is the order u solve equations.
P = parenthesis....u solve what is in parenthesis first
E = exponents...u solve the exponents next
M = multiply , D = divide....starting from left and going right, u do all the multiplying and dividing
A = addition, S = subtraction...starting from left and going right, u do all the addition and subtraction
Answer: y-5=2(x-1)
Step-by-step explanation:
Answer:
The answer is 67 degrees.
Step-by-step explanation:
The angle x is supplementary with 23 degrees because that angle is an alternate interior. Recall that is within a right angles as well so
90 - 23 = 67
