Answer:
3*6=18
7+8=15
18*15=270( that being that you have multiply after finding the answer for the two?)
Answer:
8m ×3.5m
Step-by-step explanation:
Area of rectangle= length ×width
Let the length and width of the rectangle be L and W meters respectively.
Area of rectangle= LW
LW= 28 -----(1)
L= 2W +1 -----(2)
Subst. (2) into (1):
(2W +1)(W)= 28
<em>Expand:</em>
2W² +W= 28
<em>-28 on both sides:</em>
2W² +W -28= 0
<em>Factorise</em><em>:</em>
(W +4)(2W -7)= 0
W +4=0 or 2W -7=0
W= -4 (reject) or W= 3.5
Substitute W= 3.5 into (2):
L= 2(3.5) +1
L= 7 +1
L= 8
∴ The dimensions of the rectangle is 8m ×3.5m.
Answer:
x=24 square feet per hour
Step-by-step explanation:
You divide 16 by 2 to get how many tiles that are laid in 1/3 of an hour. Then multiply that by 3 to get how many tiles in one whole hour. The answer should be 24.
Answer:
0.0000214
Step-by-step explanation:
To convert the given question to decimal point we will have to move the point by the number in the standard form...how
2.14*10^-5
It means that the point will be moved to the left in five times...
It gives 0.0000214
In some cases we might just have to move the point to the right if only the 10^-5 is just 10^5
Always ensure to be cautious of signs
The final answer is 0.0000214
