First, list all the prime factors of both terms:
23x²: 1, 23, x, and x
6x: 1, 2, 3, and x
The two numbers share the prime factors 1 and x, so the GCF of 23x² and 6x is 1x, or x.
The expression is undefined when C, x = 9.
The way that this expression can be undefined is if the denominator is 0 (dividing by 0 is undefined). To make the denominator 0, that means that 9 - x =0. That means that x = 9. So, when x = 9, the denominator is zero, meaning that the expression is undefined when C, x = 9.
Answer:
b
Step-by-step explanation:
it isn't c because theres a theorem that says that opposite angles in a parallelogram are congruent
it isn't d because if the opposite angles are 90 and 90 they are supplementary
a is correct, but for the wrong reason
its b
The answer is B. 1/3
√5/√45 <— simply both terms by 5
= √1/√9 <— √5÷5 = 1 and √45 ÷ 5 = √9
= 1/√9
= 1/3
√1 = 1
(you can write 1 directly instead of √1)
√9 = 3
Answer
Find out the what is the total distance Zohar needs to cut with the scissors .
To prove
As given
Zohar is using scissors to cut a rectangle with a length of 5x – 2 and a width of 3x + 1 out of a larger piece of paper.
As
Perimeter of the rectangle = 2(5x – 2) + 2(3x + 1)
As x = 4
Put in the above
Perimeter of the rectangle = 2 × (5 × 4 – 2) + 2 × (3 × 4 + 1)
= 2× (20 - 2) + 2 × (12 +1 )
= 2 × 18 + 2 × 13
= 36 + 26
= 62 units
Therefore total distance Zohar needs to cut with the scissors is 62 units.
