What is the surface area of the regular pyramid below?

(I didn't mean to select B)

First, find the area of its base. Since this is a square, the formula is l x w, so:

14 x 14 = 196 units^2

Next, the area of a triangle, which is b x h /2

So the hight is 20, base is 14, which means

14/2 * 20 = 7*20 = 140 units^2

But this is just the area for 1 triangle; there are four in this pyramid.

So 140 is multiplied by 4, which is 560 units^2.

Add the total area for the triangles to the square, and you get 196 + 560 = 756 units^s (B)

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
