<span>Equation A: 4c = d − 8
</span><span>Equation B: c = 5d + 8
</span>
Multiply Equation A by -5:
Equation A: - 20c = -5d + 40
Equation (1) + (2) :
-19c = 48
Answer: <span>B. Multiply equation A by -5</span>
You take the 3 squared which is 9 then, you divide that by three then you get 3
With what ? I need more instructions
Answer:
65 feet and 2 inches
Step-by-step explanation:
to find the area of a rectangle you need to multiply length times width in this case 17" times 3'10". But first you must convert everything into the same form(in this case feet) so first you can convert everything to inches by multiplying 3 times 12 which gives you 36 then add the 10, so it is now 46 inches then multiply that by 17 and altogether it is 782 inches, then divide by 12 (to convert it back to feet) and the answer is 65.1666666667. After you can round and get 65 feet and 2 inches.
