The Area is the width<span> times the </span>height<span>: A = w x h;
Then, 64 = w x h;
h = 4 + w;
64 = 4w + w^2;
w^2 + 4w - 64 = 0;
We solve this equation: w1 </span>≈ 6,24 > 0 (okay); w2 ≈ - 10,24 < 0 (not okay);
<span>Finally, h1 </span>≈ 10,24;<span>
</span>
Answer:
13
Step-by-step explanation:
Look carefully: you'll see that each new term is the sum of the previous two terms. The 3rd term is 0 + 1, or 1. The 4th term is 1 + 1, or 2. The 8th term is the sum of 5 and 8, or 13.
You can use math away it would help!
B. Half the speed of the car. and C. The number of different colors on the page.
Variables are symbols for unknown values, so you have to find the statements that contain an unknown value.
A. 27 ⇒ The point value is known, so there is no variable.
B. 
X ⇒ Since the speed of the car is unknown, the variable X represents the speed of the car. This variable is multiplied by or divided by 2 to get half the speed of the car.
C. X ⇒ The number of different colors is not known, so the variable X represents the number of different colors.
D. 80 ⇒ There is nothing unknown in the statement.
