Answer:
B
Explanation:
When multiplying exponents, you add them together.
The value of x = (- 1 + 2√2)/4 satisfies the given equation.
<h3>What is an Equation ?</h3>
An equation is a mathematical statement formed when two algebraic expressions are equated by an equal sign.
The equation given is
(4x + 1)² - 8 = 0
x = (- 1 + 2√2)/4
To check whether it satisfies the equation
( 4 * ( (- 1 + 2√2)/4) +1)² -8 = 0
(-1 + 2√2 +1)² - 8 = 0
(2√2)² -8 = 0
8-8 = 0
As LHS = RHS ,
hence the value of x = (- 1 + 2√2)/4 satisfies the given equation.

Answer: It's 35.5 and 38.5
Step-by-step explanation:
First, subtract 74 by 3 giving you 71.
Next, divide 71 by 2; it gives you 35.5 (that's your first number).
Then, add the 3 that you took away to 35.5 and get 38.5 (that's your second number).
I believe it’s 20, hope this helps!

2lb+1 3/4lb+(10oz)(lb/16oz) change the mixed number to improper fraction
2+7/4+10/16 make all have a common denominator of 16
2(16/16)+(7/4)(4/4)+10/16
(32+28+10)/16
70/16
(64+6)/16
