Answer:
Step-by-step explanation:
= (x^2 + h^2 - 2xh) + (y^2 + k^2 - 2yk) As, (a-b)^2 = a^2 + b^2 - 2ab
= x^2 + h^2 - 2xh + y^2 + k^2 - 2yk
Answer:The area of a circle with diameter 3.5 is 7
Step-by-step explanation:
In order to find b1 from your formula stated we need to do few calculations
A=hb1+hb2, as you wee I multiply h with both bases( b1 and b2)
I will subtract hb2 from both sides
hb1=A-hb2
now I will divide my new expression by h
b1=(A-hb2)/h
just add the whole numbers and add negative infront -16+-27= -43
Answer:
<h3> D) $276.26</h3>
Step-by-step explanation:
Deposited amount initially (P) = $250.
