Answers
Answer:
D. 329
Step-by-step explanation:
119 can be expressed as the factors of 2 prime numbers: 7 and 17.
There would be no need to further simplify the expression if x does not have one of these factors.
We can check that D is the only one that has one of these factors: 7, since 329/7 = 47.

Is x=-4 a solution to the equation —3z + 10 = 5?
Answers
Answer:
No.
Step-by-step explanation:
First, note that there is no variable x inside the equation. Therefore, there is nothing for the -4 to plug into.
However, if you meant to put the same variable, it still will not work.
Plugging in -4 for z (if you meant z = -4), would give you the following:
Assuming that z = -4
-3(-4) + 10 = 5
-12 + 10 = 5
-2 ≠ 5.
Therefore, even if you did mean to put the same variable, it will still not be correct.
~
For the given equation, there is no variable x but z is a variable in the linear equation. Since x is not a variable of the equation, we can't put the value given.
But if we plug the value of -4 in place of z:
➝ -3(-4) + 10
➝ 12 + 10
➝ 22 which is not equals to 5.
Hence, this equation is not satisfying for the value of variable given that is 4. Thus, -4 is not a solution to the given equation[tex].[/tex]

Answers
Answer:
2
Step-by-step explanation:
The required length of the DF on the line segment is 21 units.
Given that,
The points C, D, E, and F all lie on the same line segment, in that order, such that the ratio of CD:DE: EF is equal to 3:2:1, If CF=42,
To determine the length of the segment DF
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Total of the ratios
CF = 3x + 2x + 1x
CF = 6x
6x = 42
x = 7
Now,
DF = DE + DF
DF = 2x + 1x
DF = 2 * 7 + 7
DF = 14 + 7
DF = 21
Thus, the required length of the DF on the line segment is 21 units.

DO you know the answer ? help me out if you can
Answers
Answer:
The answer would be B. Benefit would decrease by $7,020 annually
Step-by-step explanation:
One way you can find a percentage of any number is to take the percentage and move the decimals to the left twice, 13% into 0.13. With this decimal you would multiply it by the main number you want the percentage from, $54,000. 0.13 × 54,000 would give you a product of 7,020 thus your answer.
This isn't completely necessary but if you would like to check your answer you could do this process backwards, to do such you would take your answer you received, 7,020, and divide that by your main number, 54,000. The quotient would be your percentage as a decimal 7,020 ÷ 54,000 = 0.13. Thus meaning your answer is correct.

Answers
Answer:
-3
Step-by-step explanation:
If we directly evaluate the function at -1, we get 0/0, meaning we may still have a limit to find.
In this case, factoring the polynomial at the top would be helpful.
The polynomial can be factored to (x+1)(x-2), so the function would now turn out to be (x+1)(x-2)/(x+1)
The (x+1) cancel out, leaving you with (x-2), which you can directly evaluate by plugging in x as -1:
-1-2 = -3
Quick disclaimer: the function is still undefined at -1; it's just that the function gets closer and closer to -3 as you approach -1.
I hope this helped you.

1. Put the value of x in the expression and see what the angle measure is.
m∠A = 4x +12 = 4(15) +12 = 60 +12 = 72
The angle is less than 90°, so is acute.

2. The measure of a right angle is 90°, so you have ...
4x +22 = 90
4x = 68 . . . . . subtract 22; next, divide by 4
