Answer:
(6x + 1)(x + 9)
Step-by-step explanation:
6x^2 +9 = - 55x
6x^2 + 55x + 9 = 0
55 is a pretty big number compared to either 6 or 9. Not only that, but 6*9 = 54.
So the answer is going to depend on multiply 6x together with 9
(6x + __ ) ( x + 9)
Now what goes were the underline is?
You have 54x. You need but 1 more to get 55x. So a one must go where the underline is.
(6x + 1 )(x + 9) Answer
Answer:
x = (5,0)
Step-by-step explanation:
To find the x-intercept, substitute y with 0 and solve for x.
x + 2(0) = 5
Then, simplify.
Multiply 2 by 0.
x + 0 = 5
Add x and 0.
x = 5
So, the result will be x = (5,0)
Answer:
(7,27) i hope this help even with no step by step
Step-by-step explanation:
Given:
Area of the largest square = 67 units²
To find:
The area of the smallest squares.
Solution:
Area of square = s²
s² = 67
Here hypotenuse of the right triangle = Side of the largest square
Using Pythagoras theorem,
In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.
<u>Checking possible answers:</u>
Option A: 8 and 58
Using Pythagoras theorem,
8 + 58 = 66
This is not equal to 67.
It is not true.
Option B: 7 and 60.
Using Pythagoras theorem,
7 + 60 = 67
This is equal to 67 (hypotenuse)
It is true.
Option C: 11 and 56
Using Pythagoras theorem,
11 + 56 = 67
This is equal to 67 (hypotenuse)
It is true.
Therefore 7, 60 and 11, 56 could be the areas of the smaller squares.
