Answer:
Step-by-step explanation:
In exponential multiplication, if bases are same, add the powers
xᵃ * xᵇ = xᵃ⁺ᵇ
Side = 12d⁶e⁷
Area of square = side *side
= 12d⁶e⁷ * 12d⁶e⁷
= 12* 12* d⁶e⁷ * d⁶e⁷
= 144d⁶⁺⁶ * e⁷⁺⁷
= 144d¹²e¹⁴
Now Tim gets $500 after it $45 was added to what he had last week
That means that
"What Tim earned last week" + $45 = $500
Subtract $45 from $500
$500-$45= $455
If you're not sure check your work
If I make $455 now and next week I get $45 more next week
$455+$45=$500
Next week I make $500
