Answer:
A=7.5
Step-by-step explanation:
A=a+b
2h=1+2
2·5=7.5
She has 6 quarters, 140 pennies, and 30 dimes.
6 x 25 = $1.50
140 = $1.40
30 x 10 = $3.10
$1.40 + $3.10 = $4.50
$4.50 + $1.50 = $6
1. (t-5)^2+3=t^2-10t+12+3=t^2-10t+15.
2. (a+h)^2+3=a^2+2ah+h^2+3
(a^2)+3=a^2+3. Subtracting, we get h^2+2ah.
3. (a^2)+3=a^2+3
(a-h)^2+3=a^2-2ah+h^2+3. Subtracting, we get 2ah-h^2.
