Answer:
= (2x+5)x(3x-7)
Step-by-step explanation:
The triangle in the drawing is semi equilateral. Therefore a=√(14^2-7^2)=12.12 cm
The base of a regular pyramid consists of 6 equilateral triangles. The area of each triangle is: (14*12.12)/2 = 84.87 cm^2
The base: 6*84.87=509.22 cm^2
The median is 5 and the mode is 3.
1. The total of x and 29.
This is because we see addition going on, so x+29 is the total of something
Hope this helps :)
