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)

∵ 5 × 5 = 25

∵ x × x = [tex]x^{1+1}[/tex] ⇒ multiply same base means add their powers

∴ x × x = x²

∴ 5x × 5x = 25x²

∵ 5x × -1 = (5 × -1)x

∴ 5x × -1 = -5x

∵ -1 × 5x = (-1 × 5)x

∴ -1 × 5x = -5x

∵ -1 × -1 ⇒ (-)(-) = (+)

∴ -1 × -1 = 1

∵ (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

Answer:

b

Step-by-step explanation:

Answer:

e - 50°

f - 65°

g - 115°

Step-by-step explanation:

Both triangles are 180°

So basically just add 50+65 which gives you 115 and that is 'g' cause that is the last missing piece of the left triangle.

Answer:

There are no solutions   Hope this helped<3 :)

Step-by-step explanation:

Let's solve your equation step-by-step.

3(y+2)+y=4(y−1)+9

Step 1: Simplify both sides of the equation.

3(y+2)+y=4(y−1)+9

(3)(y)+(3)(2)+y=(4)(y)+(4)(−1)+9(Distribute)

3y+6+y=4y+−4+9

(3y+y)+(6)=(4y)+(−4+9)(Combine Like Terms)

4y+6=4y+5

4y+6=4y+5

Step 2: Subtract 4y from both sides.

4y+6−4y=4y+5−4y

6=5

Step 3: Subtract 6 from both sides.

6−6=5−6

0=−1

Answer:

There is no solution

Step-by-step explanation:

First step:  

3(y + 2) + y = 4(y – 1) +9

Second step, distributing:

3y + 6 +y  = 4y -4 + 9

Third step, combining like terms:

4y + 6 = 4y + 5

Fourth step:

determine if it has a solution which it does not. How do i know?

When you continue the problem 4y + 6 = 4y + 5 you need to subtract 6 on both sides which gets you -1. then you subtract 4y on both and you get

0=1. Therefore this is definitely no solution

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.)

Answer:

x=4

Step-by-step explanation:

3x+x - 2x + 8= 3x + x

4x- 2x +8 = 4x

2x + 8= 4x

8= 2x

x=4

Answer:

  8(x +9) = 5

Step-by-step explanation:

The words "the sum of a number and 9" mean "x+9" when x is used to represent the number. The "8 times the sum" is 8(x+9). When that "equals 5", then we have the equation ...

  8(x +9) = 5

Answer:

They will each get 6 a piece

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.

Answer:

3(x+2) and 3x+6 are equivalent.

3(2x) is not.

Step-by-step explanation:

Simplify the expressions first.

1. 3(x+2) becomes 3x+6

2. 3x + 6

3. 3(2x) becomes 6x

The first and second are equivalent to each other.

The third one is not equivalent.

Step-by-step explanation:

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.

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.
