Answer:
Step-by-step explanation:
In this question we need to assume the side length of each quilt
- quilt 1: 3 cm
- quilt 2: 4 cm
Quilt 1 has the area of: 3*3 = 9 square cm and the perimeter: 3+3+3+3 = 12 cm
Quilt has has the area of: 4*4 = 19 square cm and the perimeter: 4+4+4+4 = 16 cm
So you can see the quilts have different perimeter, and areas

Answer:
<u>domain: {10,15,19,32}</u>
<u>range:{5,9,-1}</u>
Step-by-step explanation:
- As we know domain is the values of input and range is the values of output.
- Here , x is the input and y is the output.
- Thus the input values according to the given problem is : 10 ,15 , 19, and thus ,
⇒<em>The domain would accordingly be these four numbers : 10 , 15 , 19 , 32.</em>
- <u>Note that we donot have any information regarding the other values of x.</u>
- The range is : { 5,9,-1 } only as the 5 is repeated in two cases .
- Range is unique and there must be not repetition. Thus the apt answer would be :
<em>domain: {10,15,19,32}</em>
<em>range:{5,9,-1}</em>
Answer:
a) x =3 and x=5
c) x =-1 and
i) x =0 and
Step-by-step explanation:
a)
Given that the quadratic equation
x² - 8x +15 =0
The factors of 15 = 5 × 3
x² - 5x -3x +15 =0
x(x -5) -3(x-5) =0
(x-3)(x-5) =0
x =3 and x=5
c)
3 x² + 10 x +7 =0
⇒ 3x² + 3x + 7x +7 =0
⇒ 3x (x +1) +7(x+1) =0
⇒ (x+1) ( 3 x +7) =0
⇒ x =-1 and
i)
2 x ² + 9 x =0
⇒ x( 2 x + 9) =0
⇒ x =0 and 2 x = -9
⇒ x =0 and
