Answer:
<h2>
x=1.8 cm</h2>
Step-by-step explanation:
(2x)²+(x+3)²=(2x+2.4)²
4x²+x²+6x+9=4x²+9.6x+5.76
5x²+6x+9-4x²-9.6x-5.76=0
x²-3.6x+3.24=0
(x-1.8) ²=0
x-1.8=0 => x=1.8 cm
Answer:
popcorn=$1
dring=$6.75
Step-by-step explanation:
Let the popcorn = P
Let the drink = D
2*P + 3*D = 22.25
12*P + 4D = 39.00
12P + 18D = 133.5
- 14D = - 94.50
-14D/-14 = -94.5/-14
D = 6.75
6.75x3=20.25
20.25+2P=22.25
P=1
