Step-by-step explanation:
area of the rectangle =161/2
Twelve a? Do you mean 12a? Because 12a just equals 12a, there is no way else to simplify it.
Answer:
A. Function 1
Step-by-step explanation:
The slope of Function 2 can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (-8 -(-2))/(3 -0) = -6/3
__
The slope of function 1 can be found by comparing the equation to the slope-intercept equation for a line:
y = mx + b . . . . . . equation with slope m and y-intercept b
The slope of Function 1 is -7/3.
-7/3 is more negative than -6/3, so Function 1 has the more negative slope.
Answer:
74 (square) cm
Step-by-step explanation:
First, to find the surface area of both faces, make each face into two right triangles.
Use the formula A = ab/2 to find the surface area of one of the new right triangles. in this case, A = 2x3.5/2 is equal to 3.5.
Double this to find the full surface area for each face, 7 (square) cm.
Next, find the surface area of the base by multiplying the length by the width. in this case, 4x5 = 20, your base surface area.
Next, find the surface areas of the sides the same way as the base. This example has the same measurements as well. 5x4 = 20.
Last, add all of the solutions together to get the surface are of the whole object. 7 + 7 + 20 + 20 + 20 = 74 (square) cm
