An equation to match is 9+(3.5 x 2)=16
aka 9+7=16
An equivalent equation is 4+12=16, if that's what you mean.
X would be 2, if that's what you're asking for.
Sorry if this isn't what you were looking for.
Answer:
center point: (-4, 2)
radius: 8 units
Step-by-step explanation:
To find the radius of a figure in a coordinate plane, you have to do x-y where x is the starting point and y is the ending point. so in this case:
-4-(-12)
= -4+12
= 8
Answer:
138,800 points
I hope this aswered your question
Step-by-step explanation:
200x19= 3,800+(7,500x19)= 138,800
Lets get started :)
a) m(x) = (x - 5)(3 + 2x) - x² + 25
↓
Open Brackets
↓
= (x × 3) + (x × 2x) + (-5 × 3) + (-5 × 2x) - x² + 25
= 3x + 2x² - 15 - 10x - x² + 25 (Bring like-terms together in descending power order)
= 2x² - x² + 3x - 10x - 15 + 25
= x² - 7x + 10
b) In x² - 7x + 10, -7 is the sum and + 10 is the product
- 2 + - 5 = -7
- 2 × -5 = 10
So the factor of x² - 7x +10 is:
↓
(x - 2)(x - 5)
Solving ( x - 2 )( x - 5 ) = 0
↓ ↓
x - 2 = 0 | x - 5 = 0
x = 2 | x = 5
