I have to do step by step why the answer of (5x - 1) (5x - 1) is 25x^2 - 10x + 1.
How do i do it?
(5x - 1) (5x - 1)
Ans: 25x^2 - 10x + 1
Answer:
(5x - 1)(5x - 1) = 25x² - 10x + 1
Step-by-step explanation:
Let us solve the question step by step
We need to find the product of (5x - 1) and (5x - 1)
The first step multiply 1st term in 1st bracket by 1st term in 2nd bracket (5x by 5x)∵ 5 × 5 = 25
∵ x × x = [tex]x^{1+1}[/tex] ⇒ multiply same base means add their powers
∴ x × x = x²
∴ 5x × 5x = 25x²
The second step multiply 1st term in 1st bracket by 2nd term in 2nd bracket (5x by -1)∵ 5x × -1 = (5 × -1)x
∴ 5x × -1 = -5x
The third step multiply 2nd term in 1st bracket by 1st term in 2nd bracket (-1 by 5x)∵ -1 × 5x = (-1 × 5)x
∴ -1 × 5x = -5x
The fourth step multiply 2nd term in 2nd bracket by 2nd term in 2nd bracket (-1 by -1)∵ -1 × -1 ⇒ (-)(-) = (+)
∴ -1 × -1 = 1
The fifth step add them up∵ (5x - 1)(5x - 1) = 25x² + -5x + -5x + 1
∵ -5x and -5x are like term, then add their coefficients
∵ -5x + -5x = (-5 + -5)x
∴ -5x + -5x = -10x
∴ (5x - 1)(5x - 1) = 25x² + -10x + 1
∵ (+)(-) = (-)
∴ (5x - 1)(5x - 1) = 25x² - 10x + 1

I need help solving...
Answer:
x = 4
Step-by-step explanation:
Because we know both figures have the same perimeter, we can set them equal to each other.
3x + 4 + 5x + 1 + 2x + 5 = x + 13 + x + 13 + 2x + 2x
10x + 10 = 6x + 26 (Added like terms.)
4x + 10 = 26 (Subtracted 6x on both sides.)
4x = 16 (Subtracted 10 on both sides.)
x = 4 (Divided 4 on both sides.)

The scale on a map shows that 2 inches represents 15 miles. Which proportion can be used to find the actual distance,
X, represented by 30 inches on the map?
2 30
15
2 X
1530
15
2
0 30
15 X
302
Answer:
The proportion that can be used is
2 inches 30 inches
15 miles x
Step-by-step explanation:
If 15 miles is 2 inches and 30 divided by 2 is 15, you have to multiply 15 by 15 to figure out how many miles 30 inches is. Because 15 x 15 = 225, 30 inches is 225 miles. Therefore, x = 225.

Write the values of the 9s in 990.250. How are the values related?
Answer:
Leftmost 9: 900
9 between 9 and 0: 90
9 on left is worth 10 times 9 on right.
Step-by-step explanation:
990.250
The 9 at the left is in the hundreds place, so it represents 9 hundreds, so its value is 900.
The 9 between the 9 and the 0 is in the tens place, so it represents 9 tens, and its value is 90.
Since the places are right next to each other, the 9 on the left is worth 10 times the 9 on the right. Sure enough, 900 is 10 times 90.
3x + x- 2x + 8 = 3x + x
Answer:
x=4
Step-by-step explanation:
3x+x - 2x + 8= 3x + x
4x- 2x +8 = 4x
2x + 8= 4x
8= 2x
x=4
Juliet wants to read more this year. So far, she has read two books for a total of 730 pages. Juliet's goal is to read 25 pages each day for the rest of the school year. Let x represent the number of days that she has followed her plan, and let y represent the total number of pages read.
Which of the following linear equations can Juliet use to model her plan and calculate the total number of pages read?
y=25−730xy is equal to 25 minus 730 x
y=730−25xy is equal to 730 minus 25 x
y=25+730xy is equal to 25 plus 730 x
y=730+25x
Answer: y= 730+25x
Step-by-step explanation:
Given: Total pages she already read = 730
Pages read by her in 1 week = 25
Let x = number of days that she has followed her plan, and let y = the total number of pages read.
Then total pages she will read in x days = 25x
therefore , Total pages she read till now(y) =730 + 25x
Hence, the linear equations can Juliet use to model her plan and calculate the total number of pages read:
y= 730+25x

what's the answer? pls help
Answer:
The slope of the line is 1.
Step-by-step explanation:
To solve this problem, we should use the equation for slope, which is given below:
slope = m = (y2-y1)/(x2-x1)
We can now plug in two points that are given in the table.
slope = m = (9-5)/(9-5)
We can simplify our expression for slope by first computing the subtraction inside the parentheses.
slope = m = 4/4
If we simplify the expression further by dividing the numerator by the denominator, we get:
slope = m = 1
Therefore, the correct answer is slope = 1.
Hope this helps!
what is the answer? pls help
Answer:
[tex]\frac{3}{2}[/tex]
Step-by-step explanation:
For this, we shall use the slope formula:
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] ← this is [tex]\frac{rise}{run}[/tex]
Assuming this is a line, all we do is pick two consecutive points and plug them in. For example, let's take the first two points. (1, -4) and (7, 5) as they are the easiest to work with.
Let's plug in these two values:
[tex]\frac{5 - (-4)}{7 - 1}[/tex]
Simplified we get:
[tex]\frac{9}{6}[/tex]
We are now able to factor 3 out of the numerator and denominator:
[tex]\frac{3}{2}[/tex]
Thus resulting in the slope.

Andres Michael bought a new boat. He took out a loan for $24,180 at 4.5% interest for 4 years. He made a $4,650 partial payment at 4 months and another partial payment of $3,400 at 6 months. How much is due at maturity? (Do not round intermediate calculations. Round your answer to the nearest cent.)
