Answer:
The answer is x=4 or x=−10
Solutions:
(x + 3)² = 49
(x+3)(x+3)=49
x²+6x+9=49
x²+6x+9-49=0
(x-4)(x+10)
x-4=0 x+10=0
x=4 x=-10
Answer:
The circumference of the CD is approximately 38 cm
Step-by-step explanation:
The circumference of the CD can be seen as the distance around the CD.
The word "circumference" is used to describe the perimeter of circular objects.
To find an approximate value of the circumference of the CD, we will use this formula.
Circumference = π × diameter
let us take π to be = 3.142
∴ circumference = 3.142 × 12 = 37.6991 cm
we can round this up to teh nearest tenth as 38cm

Answer:
$17.97
Step-by-step explanation:
It should be no surprise that the total cost is the sum of the costs of the items being purchased.
We can add the costs of repeated items into the sum several times, or we can use multiplication to find their cost. Most folks use multiplication to find the sum of repeated numbers.
milk + strawberries + bananas
= $3.49 + 2×$4.99 +6×$0.75
= $3.49 +9.98 +4.50
= $17.97

= ( -1- -3)/( 8 - -9)
= ( -1+3)/( 8+9)
