Which of the following is equivalent to (2a+1)(2a+1)?
O (2a + 1)2
O 4a + 2
O 2(2a + 1)
O4a²+1
Answers
The equivalent expression is (2a + 1)².
Option (A) is correct.
What is a Polynomial?Polynomial, a mathematical expression made comprised of numbers and variables arranged in specific patterns. They serve as the foundation for solving algebraic equations.
As per the given data in the question:
We are given an expression, and we have to find out the equivalent expression from the given options in the question.
The expression is (2a + 1)(2a + 1)
For option (A). (2a + 1)²
In (2a + 1)(2a + 1) using associative multiplication.
= 2a.2a + 2a + 2a + 1
= 4a² + 4a + 1
Using the identity: a² + 2ab + b² = (a + b)²
4a² + 4a + 1 = (2a + 1)²
The equivalent expression is (2a + 1)².
Hence, The equivalent expression is (2a + 1)².

3x+2y=4,6x+3y=2 Solve the systems of equations by substitution
Answers
Answer:
x = -8/3, y = 6
Step-by-step explanation:
3x+2y=4 so x = (4-2y)/3
6x+3y=2
substiute x into the second equation
6((4-2y)/3) +3y = 2
2(4-2y) + 3y = 2
8 - 4y + 3y = 2
-y = -6
y = 6
Replace y into the first equation
3x + 2 (6) = 4
3x +12 = 4
3x = -8
x = -8/3
Write the equation that describes the line with slope = -8 and y -intercept = 2 in slope -intercept form (y=Mx+b).
Answers
Answer:
y=-8x+2
Step-by-step explanation:
The reason that is the answer is because the slope-intercept form is y=mx+b where m is the slope and b is the y-intercept so y=mx+b would be y=-8x+2

‐2(‐5i-4)+i+1 = 119
Answers
Answer:
i = 10
Step-by-step explanation:
-2(-5i-4)+i + 1=119
Distribute -2 into whats in the parentheses
10i+8+ i+1=119
Now combine like terms
(10i + i)+ (8+1)= 119
11i + 9 = 119
Subtract 9 from both sides
11i + 9-9= 119-9
11i = 110
Now divide by 11
11i/11 = 110/11
i= 10

Step-by-step explanation:
(9x + 29)° + (93 - 5x)° + (10x + 2)° = 180°
9x + 29 + 93 - 5x + 10x + 2 = 180
14x + 124 = 180
14x = 56
x = 4
m∠A = (9(4) + 29)° = 65°
m∠B = [93- 5(4)]° = 73°
m∠C = (10(4) + 2)° = 42°
m∠C < m∠A < m∠B
AB < BC < AC

The z-critical values are:

Step-by-step explanation:
The confidence level is, c% = 82%.
The significance level for the two tails are:
Left tailed:
[tex]\frac{\alpha}{2} =\frac{1-c\%}{2}[/tex]
[tex]=\frac{1-0.82}{2}\\\\=\frac{0.18}{2}\\\\\=0.09[/tex]
Right tailed:

The "average offer" is the average of the 5 offers: 4 that are 0 and 1 that is 10 million.

That will be misleading because the average is not very representative of the actual distribution. The actual distribution of offers is highly skewed toward lower values.
