Since this is a linear equation the rate of change or velocity is constant.  Take the derivative of y with respect to x...

dy/dx=4

This is commonly called the slope of the line.  All lines because they are straight have a constant velocity.

The slope/growth is 4.
Y= 4x+7
Figure 0 / y intercept= 7
The slope / growth = 4

kvv77 [185]
3.60 / 60cm = .06/cm or 6 cents per centimeter
100cm = 1m
$.06 * 100cm = $6.00 / m

Alex tried to find the lateral area of the pyramid. FIND HIS ERROR AND CORRECT IT.
sweet-ann [11.9K]

Answer:

His error is multiplying by 4 sides as he thought it was total surface not lateral surface area- the final answer is 12

Step-by-step explanation:

He should have multiplied it by 3, because the 3 sides- not including the base- is what lateral surface area is. He originally did total surface area not lateral surface area so each sides area is 4m squared then you just multiply it by 3 and its 12

Answer:

Step-by-step explanation:

We can split this up into 3 shapes.

Using the attached image:

A = (5-2)*(3)\\A = 3*3 = 9\\\\B = \frac{1}{2}(7-3)(5-2)\\B = \frac{1}{2}(4)(3)\\B = 2*3 = 6\\\\C = 7 * 2 = 14\\\\A + B + C  = 14 + 6 + 9 = 29
