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

Find the solution(s) for x in the equation below. x2-25=0

AleksandrR [38]

Answer:

x=12.5

Step-by-step explanation:

2x-25=0

Move 25 to the right with addition so you get the 2x by itself:

2x=25

Now divide the 2 to the right to get the x by itself:

x=25/2, which is the same as x=12.5
