Answer:

x<3,x<5

Step-by-step explanation:

This an inequality question

x^2-8x+15<0

To solve this question we will have to factorise

x^2-3x-5x+15<0

x(x-3)-5(x-3)

(x-5)(x-3)<0

x-5<0

Add 5 to both sides

x<5

x-3<0

Add 3 to both sides

x<3

Therefore x<3,x<5

Make a the subject of the formula:p=2a-3

IceJOKER [234]

To make a the subject we proceed as follows:
p=2a-3
add 3 on both sides
3+p=2a-3+3
simplifying the above gives us:
3+p=2a
divide both through by 2
3/2+p/2=(2a)/2
thus
a=3/2+p/2

emmainna [20.7K]

Step-by-step explanation:

We have,

Diameter of cylinder, d = 39.2 mm

Radius, r = 19.6 cm

Height of the cylinder, h = 39.2 mm

It is required to find the surface area of this cylinder. The formula of the surface area of cylinder is given by :

$S=2\pi rh+2\pi r^2\\\\S=2\pi r(h+r)$

Putting all values we get :

$S=2\times\dfrac{22}{7}\times19.6\cdot(39.2+19.6)\\\\S=7244.16\ mm^2$
