Answer:
Step-by-step explanation:
we know that 100 cm are equal to 1 meter
there are 4 "groups" of 25 cm in one meter
the worm needs 76 seconds to travel a meter, in case you need to know that
The square root of 16 is rational.
Hey!
So you have a net of the figure. It's broken into several 2D shapes. What you an do it find the area of each shape and add it together.
Triangles:
A = (b*h)/2
A= (5 * 3) / 2
A = 15/2
same thing for the second one
15/2 * 2 = 15
Don't forget, there are 2 triangles so it's really 15 for both
Rectangles:
A=b*h
A= 7*5
A=35
A=7*5
A=35
A=3*7
A=21
35+35+21=91
Now add the sum of the area of the triangles and the sum of the area of the rectangles
91+15 = 106
106 is the surface area
Hope this helps!
The product of a scalar and a matrix is found by multiplying each element of the matrix by the scalar. Multiply each element by -4.

Gf(x)
=g[f(x)]
=g[x2-1]
=x2-1+2
