Question

If de = 3x-15 and be =2x+10 find bd

Answer 1

Answer:

bd=-6

Step-by-step explanation:

be=3x-15 de =2x+10

be=3(x-5) de= -2(x-5)

so e= x-5

b=3

d=-2

bd=3×-2

bd=-6

Answer 2

Answer:

BD= -6.

Step-by-step explanation:

Here in this question, we have been given that DE= 3x-15 and BE= 2x+10, and we are asked to find BD.

Now we can write

DE= 3x-15

    = 3(x-5)       ---------(eq-1)

and also,

BE = 2x+10

    = -2(x-5)      ---------(eq-2)

∴ B= -2 and D=3 from equation 1 and 2.

Now,

BD = -2×3 = -6

Hence BD= -6.
