Answer:
Let's simplify step-by-step.
(−a)(−4 − 5a) − 3a(2 + a)
Distribute:
= (−a)(−4) + (−a)(−5a) + −3a^2 + −6a
= 4a + 5a^2 + −3a^2 + −6a
Combine Like Terms:
= 4a+5a^2 + −3a^2+ −6a
= (5a2+ −3a^2) + (4a + −6a)
= 2a2 + −2a
Final Answer:
= 2a^2−2a!
4¾=19/4 and 11⅞=95/8.
Width=area/length=95/8÷19/4=95/8×4/19=5/2=2½ft.
8 can go as much as 8.125 or 8 1/8 times in 65. This is done by using a basic mathematical operation which is division. 65 is divided by 8 which will give us the answer of 8.125 or in fraction form it would be 8 1/8.
Answer:
2.4
Step-by-step explanation:
12x2.4 = 28.8 (Area)
12+12+2.4+2.4 = 28.8 (Perimeter)
Hmmm.. I solved it and got 82%. I may be wrong, but try it out.
