Answer:
x^2 + 10x + 25; (x + 5)^2.
Step-by-step explanation:
When we're talking about line segments, we just have to find the sum of the two parts of the line segment to find the value of the whole. In this case, we have x^2 + 25, and 10x. So, we add them together.
x^2 + 25 + 10x
= x^2 + 10x + 25
Since this can be immediately factored into (x + 5)^2, you have your answer.
Hope this helps!
Answer: b=5
Step-by-step explanation:
Multiply all terms by b and cancel:
3b/5+2=1b
3/5b+2=b(Simplify both sides of the equation)
3/5b+2−b=b−b(Subtract b from both sides)
−2/5b+2=0
−2/5b+2−2=0−2(Subtract 2 from both sides)
−2/5b=−2
(5−2)*(−25b)=(5−2)*(−2)(Multiply both sides by 5/(-2))
b=5
Check answers. (Plug them in to make sure they work.)
b=5 (Works in the original equation)
Answer:
b=5

c. For David to achieve three hundred dollars, he would have to save approximately 5 months
Step-by-step explanation:
A. David requires three hundred dollars, this is his goal, indicating the three hundred must be alone. For the inequality sign, the statement says that he "requires at least $300", meaning that he would have to maintain three hundred dollars or his amount could go greater than $300. Therefore, the inequality sign should be "≥" or "greater than or equal to". We also know that David can save 63 dollars per month, meaning that there should be a variable next to 63 so we could replace "x" with any number to solve our inequality. This should leave us with the following inequality :
63x ≥ 300
B. To solve the inequality, we need to get x alone, to do so, divide 63 by both sides,


To make it easier, we can round "4.76" to 5.
