Answer
given equation,
x⁵²-21 x+20
A number to be divisible by the another number means that on dividing the remainder should be zero.
if x⁵²-21 x+20 is divisible by x− 1 means that x-1 should completely divide the equation.
so,
x -1 = 0
x = 1
x⁵²-21 x+20 to be divisible it should be equal to zero when x = 1
putting x = 1
= (1)⁵²-21 (1)+20
= 1 - 21 + 20
= 21 -21
= 0
hence x = 1 is the root of the equation
so, x⁵²-21 x+20 is divisible by x− 1.
That would be the same as : 10 × (x + 8)
Okay, so it's asking for the product of 10, and the sum of 8 and k. Sum is the answer to an addition problem, so that would make the last of it 8 + k. And we'd be multiplying this with 10, so that would make it : 10 × (x + 8)
Not A for sure but I’m not positive which other one it would be.
Answer: the correct answer is A. banked with dirt to a height of
Step-by-step explanation:
More than parallelism, this topic is more related to the correct use of prepositions. Here when it is better to use banked with dirt because it means overlaid with dirt,; it is not necesary to ad any other word. Then, we say to a height of when we want to say how high something is and we ad a number after that.
x(y) is the same as saying "x times y". The x and y are placeholders for numbers. Think of them like boxes to place a number inside. In this case, we place an "8" in the box labeled "x"; we also place a "23" in the box labeled "y"
So, x*y = 8*23 = 184
Answer: 184
