Answer:
width = 3.5 feet length = 8 feet.
Step-by-step explanation:
W=x
L=2x+1
Area=(2x+1)x=28
2x^2+x=28
2x^2+x-28=0
(2x-7)(x+4)=0
x=3.5,-4. It should be a positive number so W=3.5
2x+1=8 2x3.5=7 7+1 = 8 L=8
That area is 28 ft^2
width is 3.5 feet and length is 8 feet.
Janet invested $6000 at 2 %.
Let <em>x</em> = amount invested at 2 %. Then 10 000 - <em>x</em> = amount invested at 12 %
interest at 2 % + interest at 12 % = 600
0.02<em>x</em> + 0.12(10 000 –<em> x</em>) = 600
0.02<em>x</em> + 1200 – 0.12<em>x</em> = 600
0.10<em>x</em> = 600
x = 600/0.10 = 6000
Answer:
No
Step-by-step explanation:
negative numbers work the opposite of how positive numbers work. Think about it like this. -12 is 12 units less than 0 and -12.5 is 12.5 units less than 0 which means that -12.5 is less than -12
