I will give you 45 for this what is 12*12/12-3/4

11.25

Step-by-step explanation:

12*12/12-3/4

PEMDAS says multiply and divide first

from left to right

144/12 - 3/4

12 -3/4

12 - .75

Then add and subtract

11.25

Step-by-step explanation:

Apply PEDMAS

P - parenthesis

E - exponents

D - division

M - multiplication

A - addition and S - subtraction  

Division is first.

12 × -

12 × 1 -

Followed by multiplication.

12 -

Subtract the numbers next.

Make the denominators same by LCM.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
