1.4 + 1.4 = 2.8
25.2 + 2.8 =28
Answer:
−63t2−439t−741
Step-by-step explanation:
Let's simplify step-by-step.
9(4+t)−7(t+3)(9)(4+t)−7(t+3)
Distribute:
=(9)(4)+(9)(t)+−63t2+−441t+−756+(−7)(t)+(−7)(3)
=36+9t+−63t2+−441t+−756+−7t+−21
Combine Like Terms:
=36+9t+−63t2+−441t+−756+−7t+−21
=(−63t2)+(9t+−441t+−7t)+(36+−756+−21)
=−63t2+−439t+−741

Convert the decimal decimal to a fraction by placing the decimal over a power of ten. since there are 4 numbers to the right of the decimal point, place the decimal number over 10^{4} (10000)
so your answer is 2777 over 10,000
