Step-by-step explanation:
Because in (x + 5)2 you have to multiply 2 by each term in the parentheses, and that is not equal to x2 + 25. itll be 2x + 10 and that is not equivalent.
x² + 25 is not equal to (x+5)² because the later has an extra term 10x in it.
What is a quadratic equation ?A quadratic equation has a highest degree of 2 and it has two solutions or roots which satisfies ax² + bx + c = 0.
According to the given explain why x² + 25 and (x+5)² are not equal.
We know (a+b)² = a² + 2ab + b².
So, (x+5)² = x² + 10x + 25.
On the other hand x² + 25 can be written as x² + 5².
∴ (x+5)² ≠ x² + 5².
There is an extra term 10x in (x+5)² or we can say x² + 25 is 10x less than (x+5)².

Answer:
628
Step-by-step explanation:
Well, if you x's are multiplication signs, then the answer is 628 because
6x100=600, 1x10=10, 7x1=7, 9x1=9, 2x1=2 and then add them all up:
600+10+7+9+2=628
Answer:
628
Step-by-step explanation:
6x100= 600
1x10= 10
7x1= 7
9x1= 9
2x1= 2
600 + 10 = 610

What is the value of x in the figure?
A. 10
B. 6
C. 15
D. 12
Answer:
Step-by-step explanation:
You need to set up a proportion.
(21 - 15) / 21 = 4/(x + 4)
6 / 21 = 4/(x + 4)
2/7 = 4/(x + 4)
2(x + 4) = 7*4
2x + 8 = 28
2x + 8-8= 28 - 8
2x = 20
x = 20/2
x = 10

The slope of a line is 6 and it goes through the point (4,5), which function is best
represented by this graph?
y = 6x - 29
y = 6x + 19
y = 6x - 19
y =6x + 29
Answer:
[tex]y=6x-19[/tex] is the function which best
represented by this graph.
The graph is also attached.
Step-by-step explanation:
As the point-slope form is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope
Given
m = 6 and the point (4, 5)
substituting the values in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - 5 = 6 (x - 4)[/tex]
[tex]y - 5 = 6x-24[/tex]
[tex]y=6x+5-24[/tex]
[tex]y=6x-19[/tex]
Therefore, [tex]y=6x-19[/tex] is the function which best
represented by this graph.
The graph is also attached.

Danny charges $22 for 2 hours of swimming lessons, Martin charges $90 for 5 hours of swimming lessons. Who offers a better deal?
Answer:
danny
Step-by-step explanation:
Danny charges $11 a hour while martin charges $18 a hour
Answer:
Danny offers a better deal
Step-by-step explanation:
Because you have to find out how much each person is charging for each hour of swimming lessons divide Danny's $22 by 2 to get $11 for one hour. And divide Martin's $90 by 5 to get $18 for one hour. Danny is giving you a better deal than Martin.

Identify the property on this equation 5(a + 3b) = 5a + 15b
Answer:
??????????????????????
Step-by-step explanation:
Answer: Distributive Property
The term "distribution" is also used in place of "distributive"
This property says
x*(y+z) = x*y + x*z
We multiply the outer term x with each inner term (y and z). Then we add the results.
In this case,
x = 5
y = a
z = 3b
So,
5(a+3b) = 5*a + 5*3b = 5a+15b
Luis rides his bicycle 34 mile in 15 minutes, or 14 hour, along the bike trail.
Assuming he rides at a constant rate, what is his speed, in miles per hour? Use the table to help find the answer.
Enter your answer in the box.
Miles 34 ?
Hours 14 ?
miles per hour
Luis' speed in miles per hour is 136.
What is speed?Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is travelling along a route.
By dividing the miles he cycled by the hours he traveled, one may calculate Luis' speed in miles per hour.
Because the measurement must be in miles per hour,
the time would be expressed in hours rather than minutes.
Speed = distance / time
Distance = 34 miles
Time = 15 minutes.
Speed = 34 ÷ 15 miles per minute.
Speed = 34 ÷ 1/4 miles per hour.
Now, speed = 34 x 4 miles per hour.
Therefore, Luis' speed is 136 miles per hour.

I need help
========================================================
Explanation:
The two points on this line are (-1,5) and (0,1)
Let's use the slope formula
m = (y2-y1)/(x2-x1)
m = (1-5)/(0-(-1))
m = (1-5)/(0+1)
m = -4/1
m = -4
The slope is m = -4
If we started at (-1,5) and moved down 4 and to the right 1, then we arrive at (0,1). The motion "down 4, right 1" is directly tied to the slope -4 since -4 = -4/1 = rise/run
The y intercept is b = 1 since this is the location where the graph crosses the y axis.
With m = -4 and b = 1, we go from y = mx+b to y = -4x+1
