Answer:
7.4% increase (approximated)
Step-by-step explanation:
✔️Dimension of the original rectangle:
Length = 30 cm
Width = 20 cm
Perimeter = 2(L + W) = 2(20 + 30) = 2(50) = 100 cm
✔️Dimension of new rectangle:
Length is increased by 10% = 10/100 × 30cm = 3 cm
New length = 30 + 3 = 33 cm
Width is increased by 5% = 5/100 × 20cm = 1 cm
New width = 20 + 1 = 21 cm
✔️Perimeter of New rectangle = 2(L + W) = 2(33 + 21) = 2(54) = 108 cm
✔️Percentage increase in the perimeter of the rectangle = (perimeter of New rectangle - perimeter of original rectangle)/perimeter of original rectangle × 100
= (108 - 100)/108 × 100
= 8/108 × 100
≈ 7.4% increase

Factorise x^2+11x+18
Answers
Answer:
(x + 9)(x + 2 )
Step-by-step explanation:
Sum =11
Product = 18
Factors = 9 , 2
When you multiply (9*2 = 18) and when you add (9 +2 = 11).
x² + 11x + 18 = x² + 9x + 2x + (9*2)
=x(x + 9) + 2(x + 9)
= (x + 9)(x + 2 )
Answer:
(x+9) (x+2)
Step-by-step explanation:
x^2+11x+18
x^2+9x+2x+18
x(x+9)+2(x+9)
(x+9) (x+2)

What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have the equation of line as -
y = 3x + 7
Refer to the graph attached of the equation -
y = 3x + 7.
Since, the graph is not given we will mark two random points on it. It can be seen that the missing [x] - coordinate of point A is -2 and point B is -1.
Therefore, the missing [x] - coordinate of point A is -2 and point B is -1.

A rectangular lot is 125 yards long and 80 yards wide.
Give the length and width of another rectangular lot that has the same perimeter but a larger area.
Answers
Answer:
Step-by-step explanation:
perimeter=2(125+80)=2(205)=410 yards
let the length of new rectangle be x and y.
Perimeter=2(x+y)
2(x+y)=410
x+y=410/2=205 yards
y=205-x
area A=xy=x(205-x)=205x-x²
[tex]\frac{dA}{dx} =205-2x\\\frac{dA}{dx}=0,gives~205-2x=0\\x=\frac{205}{2}\\\frac{d^2A}{dx^2}=-2<0 ~at~x=\frac{205}{2}\\[/tex]
A is maximum at x=205/2
y=205-205/2=(410-205)/2=205/2
so x=205/2=102.5 yards
y=205/2=102.5 yards

Answer:
Another ratio that is equivalent to this is 7:2.
Step-by-step explanation:
If we divide both sides by 6, we get 7 and we get 2. Since 42 comes first, we put the 7 in place of the 42. Then we replace 12 with 6. After this, we get the ratio 7:2.
