The length of a side of a square is 4x – 1.
Express the area of the square in terms of x.
Answer:
16x^2 - 8x + 1
Step-by-step explanation:
1. The area of a square can be represented as s^2 or (s)(s), where s = side.
2. (Solving)
Step 1: Set up expression
[tex](4x-1)^2[/tex] [tex](4x-1)(4x-1)[/tex]Step 2: Apply the FOIL method (first, outside, inside, last)
[tex](4x)(4x)+(4x)(-1)+(-1)(4x)+(-1)(-1)[/tex] [tex]16x^2 -4x -4x +1[/tex]Step 3: Simplify.
[tex](16x^2)+(-4x-4x)+(1)[/tex] [tex]16x^2 -8x + 1[/tex]Therefore, the area of the square in terms of x is 16x^2 - 8x + 1.
Last
year at a certain high school, there were 60 boys on the honor roll and 130 girls
on the honor roll. This year, the number of boys on the honor roll increased by 5%
and the number of girls on the honor roll increased by 20%. By what percentage did
the total number of students on the honor roll increase? Round your answer to the
nearest tenth (if necessary).
Answer:
15.3%
Step-by-step explanation:
60x.05 = 3 boys
130x.20 = 26 girls
3+26 = 29 students
60+130 = 190 total students
(29/190)*100 = 15.3%

Answer:
32
Step-by-step explanation:
to form a linear pair means when the two angles are added, they equal 180 degrees
3x + 20 + x + 32 = 180
4x + 52 = 180
4x = 128
x = 32

Step by step :x² = 12² + 10²
x² = 144 + 100
x² = 244
x = 15,6m✔
x² = 12² + 10²
x² = (12 × 12) + (10 × 10)
x² = 144 + 100
x² = 244
x = √244
x = 15,6 m
-0.1b = 3.8, what is b?

Answer:
N/A
Step-by-step explanation:
We should first simplify the right side, and doing so will get x/3+6=x/3+10. WE then subtract x/3 on both sides to get 6=10. Since this cannot be true, there are no solutions.
Answer:
no solution
Step-by-step explanation:
[tex]\frac{x}{3}[/tex] + 6 = 2([tex]\frac{x}{6}[/tex] + 5) ← distribute parenthesis by 2
[tex]\frac{x}{3}[/tex] + 6 = [tex]\frac{x}{3}[/tex] + 10 ( subtract 6 from both sides )
[tex]\frac{x}{3}[/tex] = [tex]\frac{x}{3}[/tex] + 4 ( subtract [tex]\frac{x}{3}[/tex] from both sides )
0 = 4 ← False statement
This indicates the equation has no solution

when 7 is added to 3 times a number, the sum is multiplied by 2 and 15 is subtracted what is the final answer
Answer:
2(3x+7) -15
Step-by-step explanation:
Let x = unknown number
7 is added to 3 times a number
3x+7
Multiply the sum by 2
2(3x+7)
Subtract 15
2(3x+7) -15
Answer:
Let the required number be " x "
Now, 7 is added to 3 times a number : (3x + 7)
Next, the sum is multiplied by 2 : 2(3x + 7)
And then, 15 is substracted from it : 2(3x + 7) - 15
2(3x + 7) - 15 is the final answer.help with this question
