21 is the length of the rectangle
Answer:
The answer is
<h3>
</h3>
Step-by-step explanation:
2x² = - x² - 5x - 1
<u>Rearrange the terms and simplify</u>
That's
2x² + x² + 5x + 1 = 0
3x² + 5x + 1 = 0
Using the quadratic formula solve the equation
That's
<h3>
</h3>
From the question
a = 3 , b = 5 , c = 1
So we have
<h3>
</h3>
We have the final answer as

Answer:
y = -4x+7 is the equation simplified and answer choice A is the right answer.
Step-by-step explanation:
Your equation: y - 6 = -4(x+1)
Your Objective: You need to simplify the original equation and find another equation that is equivalent to the original equation.
Let's focus on the -4(x+1) side first.
This needs to have the distributive property applied.
Take -4 and multiply it by x and 1.
You should have -4x+1
Your equation now:
y - 6 = -4x+1
We want y to be by itself.
So add 6 to both sides.
y = -4x+1+6
Use PEMDAS
y = -4x+7
The first answer choice "A" is correct.
Answer:
Walter earns $1,517 more than Stevens in one year.
Step-by-step explanation:
Giving the following information:
Two brothers Steven and Walter each inherit $41,000
Steven:
Annual return= 2.7%
Walter:
Annual return= 6.4%
<u>To determine the future value for the brothers, we need to use the following formula:</u>
FV= PV*(1+i)^n
Steven:
FV= 41,000*1.027= $42,107
Walter:
FV= 41,000*1.064= $43,624
Difference= 43,624 - 42,107= $1,517
Walter earns $1,517 more than Stevens in one year.
