Answer:

Option B is true

Step-by-step explanation:

We are given that three right  triangles .Triangles ABD,CAD and CBA are similar.

When two triangles are similar then, the corresponding sidea are in equal proportion.

We have AB=5 units

AC= 7 units

BC=x

Triangles ABD is similar triangle CBA

\frac{AB}{BD}=\frac{BC}{AB}

AB^2=BC\cdot BD

(5)^2=BC\cdot BD

BC\cdot BD=25

When triangle CAD and CBA are similar

Then,\frac{AC}{BC}=\frac{CD}{AC}

AC^2=CD\cdot BC

(7)^2=CD\cdot BC

49=CD\cdot BC

In traingle CBA, uisng pythagoras theorem

AB^2+AC^2=BC^2

BC\cdot BD+BC\cdot CD=x^2

25+49=x^2

x^2=74

Hence, option B is true.

X^2 -3x + 0 = 0 Factor and solve
Luda [366]
So if you subtract the 0 out from the left side, the equation is now x^{2}-3x=0. Since a x is common in both of the terms on the left side, you can factor it out, now making the equation look like x(x-3)=0. When factoring, each of the separate things (x and (x-3)), must equal zero while the other one doesn't matter. So in order for the equation to be 0, the only potential options for x is 0 and 3. Therefore x=0 and x=3 are the two solutions

a system of equations is shown below: equation a: 2c = d − 8 equation b: c = 3d 8 which of the following steps should be perform
Fofino [41]
If you would like to know which of the following steps should be performed to eliminate variable d first, you can find this using the following steps:

equation a: 2c = d - 8      /*(-3)
equation b: c = 3d + 8
__________________
-6c = -3d + 24
c = 3d + 8
__________________
-6c + c = -3d + 24 + 3d + 8
-5c = 32
5c = -32
c = -32/5

<span>The correct result would </span>be: <span>multiply equation a by −3.</span>

You're phrasing it, so it shouldn't be much longer than the actual line. It should just be your interpretation.
