X2-1 I think that's the answer because there's 1 less, 1 take away the x and squared!! hard to explain but that's how I thought about it
Answer:
The answer is attached as an image.
Step-by-step explanation:
- If we assume that the space is 100% of the population then:
88% have something and 12% have nothing.
So within the 88% there are 10% who have TV, 20% who have Radio and 58% who have both TV and Radio.
Answer:
perimeter-
perimeter outer rectangle = 2 (l+b)
=2×8+9
= 2×17
2×17 =34 cm sq.
perimeter of inner rectangle = 2 (l+b)
= 2×5+3
=2× 8
= 16 cm sq.
perimeter of shaded portion= 34 - 16
= 18 cm sq.
area-
<em>area</em><em> </em><em>of</em><em> </em><em> </em><em>inner</em><em> </em> rectangle =l×b
l×b = 3×5
3×5=15
15 cm sq.
area of outer rectangle =l×b
l×b= 9×8
9×8= 72
72 cm sq.
area of shaded portion = 72 -15 =57 cm sq.
hey there! In second method i have done first area of inner rectangle but you have to do first area of outer rectangle...
hope it helps you....
Answer: D) 3x - 5
Step-by-step explanation:
f(x) - g(x)
f(x) = 1/2x - 3
g(x) = -5/2x + 2
Using the values of f(x) and g(x) gives us the equation:
1/2x - 3 - (-5/2x +2)
By distributing the negative sign, the signs on 5/2 and 2 are flipped, making them positive and negative respectively.
Our new equation is:
1/2x -3 + 5/2x -2
Adding up like numbers gives us:
6/2x - 5
Simplifying 6/2x => 3x
So our final equation is:
3x - 5
Hope this helps!
Answer: 12 miles
Step-by-step explanation:
Hi, to answer this question we have to write a growth equation.
Total miles = 8 (1 +0.05)^9 = 12.41 =12 miles
Where 8 is the initial miles she run, since is increasing each week by 5% we have to multiply it by 1+ percent increase rate in decimal form (1+0.05) to 9th power (number of weeks)
She will run 12 miles in 9 weeks.
