Check all that are equivalent A=1/2h(b1+b2), 2A=hb1+b2, b1=2A/h-b2, b1=2(A-1/2hb2)/h
VMariaS [17]

Answer:

(A)A=\dfrac12h(b_1+b_2)

(D)b_1=\dfrac{2(A-\dfrac12 hb_2)}{h}

Step-by-step explanation:

Given that:

A=\dfrac12h(b_1+b_2)

2A=h(b_1+b_2)\\2A=hb_1+hb_2\\hb_1=2A-hb_2\\b_1=\dfrac{2A-hb_2}{h} \\b_1=\dfrac{2(A-\dfrac12 hb_2)}{h}

Therefore, A and D are equivalent
