think about two numbers that will get 25:
think about two numbers that will get 10
use the 5 times tables
5*5= 25
Use 5+5= 10
x^2+10x-25= 0
(x+5)(x+5)= 0
x+5= 0 , x+5= 0
x+5-5= 0-5
x= -5
x+5-5= 0-5
x= -5
Answer :
only x= 5
The area of the of the storefront window made of glass in question is = 154 square feet
The length of the glass window that is given in the question is = 7 feet
Let us assume the Width of the glass window in question to be = x feet
Then
Area = Length * Width
154 = 7 * x
7x = 154
x = 154/7
= 22 feet
So we come to know that the width of the glass window in question is 22 feet.
Now
Perimeter of the glass window = 2 ( Length + Width)
= 2 (7 + 22) meters
= 2 * 29 meters
= 58 meters.
So the perimeter of the glass window as can be seen from the above deduction is 58 meters.
Answer:
Equivalent
Step-by-step explanation:
Look at 6/18. 18 divided by 6 is 3, which is the denominator. 6 divided by 6 is 1, so the numerator. So 1/3.
Answer:
7pi or ≈21.98 cm²
Step-by-step explanation:
The area of the shaded and non shaded in the circle is pir^2 so pi3^2 so 9pi
the area of the 2 smaller circles is pi1^2*2 so 2pi
9pi-2pi=
7pi cm² =
7pi≈21.98 cm² (with pi as 3.14)
Answer: y = -x - 8
Step-by-step explanation:
y = -x - 8
slope = -1/1
yint = -8
