Find the area please

GalinKa [24]

The area is 220 because 8 times 20 is 160. and 6 times 20 is 120 divided by 2 is 60. then 160 plus 60 equals 220.

Can you please help me on this question-2(t-4)=10-2t

sveta [45]

Answer:

No Solution

Step-by-step explanation:

Step 1: Distribute

$-2(t - 4) = 10 - 2t$

$(-2 * t) + (-2 * -4) = 10 - 2t$

$-2t + 8 = 10 - 2t$

Step 2: Add 2t to both sides

$-2t + 2t + 8 = 10 - 2t + 2t$

$8 = 10 + 0$
