Answer:
<h2><em><u>320</u></em><em><u>0</u></em><em><u> </u></em><em><u>cm</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
Length of the rectangle = 12 meters = 1200 cm
Width of the rectangle = 400 cm
<em><u>Therefore</u></em><em><u>, </u></em>
Perimeter of the rectangle = 2(l+w)
= 2(1200+400) cm
= 2 × 1600 cm
= <em><u>320</u></em><em><u>0</u></em><em><u> </u></em><em><u>cm</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
Answer:
108
Step-by-step explanation:
2/3x+4=76
2/3x=72
x=72*3/2
x=108
8 divided by 1/4 (25%) is 2. Therefor, it would be 10 meters.
Answer is 49
Formula is b^2-4(ac)
3^2-4(2*-5) while a=2, b=3, c=-5
9-4(2*-5)
9-4(-10)
9+40
49
Hope this helps!
(-2 + 0.8) ÷ (1²-1.3) =
(-1.2) ÷ (1-1.3)
(-1.2) ÷ (-0.3)
= 4
