Question:
Solve the equation 2x2−5x+3=0 by the method of completing square.
Answer:
We have,
2x2−5x+3=0
⇒x2−25x+23=0 (Dividing throughough by 2)
⇒x2−25x=−23 (Shifting the constant term on RHS)
⇒x2−2(45)x+(45)2=(45)2−23 (Adding (21Coeff.ofx)2 onboth sides)
⇒(x−45)2=1625−23⇒(x−45)2=16
8 $10 bills and 11 $5 bills. 8 times 10 is 80 and 11 times 5 is 55 and 80 plus 55 is 135.

Step-by-step explanation:
9 is 3/4 of 12, and it is scaled down, so the answer should be 3/4
Answer:
2. 113.0 yd²
Step-by-step explanation:
Circumference Formula: C = 2πr
Area of a Circle Formula: A = πr²
Since we are given circumference, simply plug it in to find radius <em>r</em>:
Step 1: Find <em>r</em>
37.68 = 2πr
r = 37.68/2π
r = 5.99696
Step 2: Find area
A = π(5.99696)²
A = 112.983
