The area of a rectangle is:
A = length × width
A rectangular television screen has an area:
A = w² + 2w inches²
width = w
length = A / width = (w² + 2w) / w = w(w + 2) / w = <u>w + 2</u>
Ansver:
<h2><u>
length = w + 2</u></h2><h2><u>
</u></h2><h2><u>
</u></h2>
The given expression is :
2xx+3-5(x-2)
We know that, 
Aleena expands 2xx+3-5(x-2) as 2x²+3-5x-10. She is mistaken because the sign before 10 should be +10 instead of -10. Hence, the correct expanded form is 2x²+3-5x+10. Hence, this is the required solution.
Answer:
x=5 y=-6
Step-by-step explanation:
3x+y=9 ------eqn1
y=4-2x -------eqn2
using substitution
put y=4-2x into eqn1
3x+4-2x=9
x=5
put x=5 into eqn2
y=4-2(5)
y=4-10
y=-6
Answer: $9.26
Step-by-step explanation:
The total cost for each of their smoothies was:
= 4.95 * 2
= $9.90
Including taxes it will rise to:
= 9.90 * (1 + tax)
= 9.90 * (1 + 8.5%)
= $10.74
Change she will receive is:
= 20 - 10.74
= $9.26
The run can be made 11 meters long
