Answer:

BC = 23.8

Step-by-step explanation:

See the diagram attached.

Given AC ║ DE and BD = 5, DA = 12 and BE = 7.

We have to find BC.

Since, AC ║ DE, so, Δ ABC and Δ DBE are similar.

If two triangles are similar then the ratio of their corresponding sides remains the same.

Hence, \frac{BD}{BA} = \frac{BE}{BC}

⇒ \frac{5}{12 + 5} = \frac{7}{BC}

⇒ BC = \frac{7 \times 17}{5} = 23.8 (Answer)

x =1

1/6x = 8/3 ( Divide both sides by <em>1</em><em>/</em><em>6</em><em> </em>)

___ ___

1/6 1/6

(By cross-multiplying the numerators and denominators)

=> 1×6 8×6

___ x = ___

6×1 3×1

Cancelling out , we have

x = 8×2

____ = 8×2 = 16

Lady bird [3.3K]

Answer:

428 square inches

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Surface area of a prism: 2wl +2lh+2hw

Where w is the width of the prism; l the length; and h the height.

Replacing with the values given:

S (smaller prism) = 2 (4x6) + 2(6x2)+ 2(2x4)=48+24+16= 88 in2

S (larger prism) = 2 (8x10) +2 (10 x5)+2(5x8)= 160+100+80=340in2

Adding both surface areas:

88+340 =428 in2

Feel free to ask for more if needed or if you did not understand something.
