Let L be the length and W be the width. 
"the width of a rectangle is half as long as the length"
W = (1/2)·L
"the rectangle has an area of 18 square feet"
A = L·W = 18
Substitute, 
L·W = 18
L·(1/2)·L = 18
(L²)/2 = 18
L² = 36
L = 6 feet
then W = (1/2) · L
W = (1/2) · 6
W = 3 feet

What is 185% of 38?<br><br> 7.03<br><br> 70.3<br><br> 703<br><br> 7030
Lilit [14]

Answer:

B) 70.3

Step-by-step explanation:

You can solve this question two different ways.

One way is to find 85% of 38 by doing 38 × 0.85, which is 32.3. Then, you can add that to 38 (since 100% of 38 is 38) and get 70.3.

Another way you can find this (the easiest way) is to just find 185% right off the bat by doing 38 × 1.85 and get the answer of 70.3.

F(x)=x^2 is vertically stretched by a factor of 2 and translated by 3 units left to create g(x). What does g(x)= ?
gavmur [86]

g(x)=-2(x+3)^2

The -2 in front is the vertical stretch.

Also, because it is going 3 units to the left, you have to put the 3 on the inside and because it is left you do the opposite and it is +3.
