Answer:
(u+3)(u-3)
Step-by-step explanation:
u²-9 = u²-3²
a²-b²=(a+b)(a-b)
u²-3²=(u+3)(u-3)
Answer:
The required option are
Length = 4 and width = x+5
Length = 2 and width = 2x+10
Step-by-step explanation:
Area of the rectangle = Length × width
Given
Area = 4x+20
Factoring out the common terms
Area = 4x + 4(5)
Area = 4(x+5)
Length = 4 and width = x+5
This can also be written as
Area = 2(2x+10)
Length = 2 and width =2x+10
Answer:

Step-by-step explanation:

Answer: B. one-third
Step-by-step explanation:
Probability of picking a red marble, P(R) = 1/6
Probability of picking a yellow marble, P(Y) = 1/2
Therefore, the probability of picking a blue marble will be:
= 1 - (P(R) + P(Y))
= 1 - (1/6 + 1/2)
= 1 - (4/6).
= 1 - 2/3
= 1/3
The probability of picking a blue marble will be one third
