Answer:
X=3
Step-by-step explanation:
0.05(4x) + 0.1x = 0.90
0.2x + 0.1x = 0.90
0.3x = 0.90
x = 3
Answer:
Perimeter of rectangle added 2 to length:
perimeter of rectangle= length + width + length + width
P = ( l + 2 ) + w + ( l + 2 ) + w
P = 2 ( l + 2 ) + 2 w
P = 4 + 2 l + 2 w
Perimeter of rectangle added 2 to width:
P = l + w + l + w
p = l + ( w + 2) + l + ( w + 2)
p = 2 l + 2 ( w + 2)
p = 2 l + 2 w + 4
<span><span>The average rate of change formula is basically the slope formula, where you plug in: f(b)-f(a)/b-a. Then plug in the numbers. [f(0)=1,f(3)=7)]. So, 7-1/3-0. 6/3 is 2 so the average rate of change is 2. And that makes sense because the average rate of change is always the slope, and the slope is 2.</span></span>
