Answer: b)
Step-by-step explanation:
You can rule out A) and C), because you have to find area (no adding.)
To do this problem, you can individually multiply the estimated hieght and
width by 3 and then multiply together.
This is because there are 3 walls that each are 9 3/4 tall and 14 1/4 wide. To find total height and width, multiply by 3. Then find total area (lxw)
9 3/4 rounds to 10
14 1/4 rounds to 14
= 3 (10) x 3 (14)
D) is incorrect because you have to multiply each number by 3. (Or you can multiply by 6)
It is B)
Answer:
88unit^2
Step-by-step explanation:Area=
1/2(17+27)*4
Area=88unit^2
Answer:
No solutions
Step-by-step explanation:
|-2x-10| + 4 = 2
Subtract 4 from each side
|-2x-10| + 4-4 = 2-4
|-2x-10| = -2
The absolute value is negative so there are no solutions.
Absolute values are always positive, so they cannot be negative.
Answer:
n+2
Step-by-step explanation:
This is a Typical Question on Arithmetic Progression with initial term as 2n+1
The next number in this particular series will be 2n+1+2 which is 2n+3 and so on. Thus a common difference of 2 exists.
The nth term of an Arithmetic Progression AP, bn is represented below where b1 is the first term
bn=b1 +(n-1)d where d is the common difference
For this particular series, the 4th term b4 is
b4= 2n+1+(4-1)2 0r b4 =2n+1+6=2n+7
sum of series is represented by equation: n(b1 +b4)/2 where b1 and b4 are 1st and 4th term respectively
Thus Sum required =4(2n+1+2n+7)/2=4(4n+8)/2=8n+16 0r n+2
Answer:
29
Step-by-step explanation:
f(x)=8(x−3)+13
f(5)= 8(5-3)+13
f(5) = 8(2) +13
f(5) = 16 +13
f(5)= 29
