Distribute the brackets to get all your terms and then combine like terms to simplify your expression.
(X+2)(x+2)
= x^2 + 2x + 2x + 4
= x^2 + 4x + 4
Answer:
1156
Step-by-step explanation:
When Deucalion threw one stone over his shoulder, 8 people appear. So, for every stone, we have 8 new people.
Therefore, if Deucalion threw 68 stones, the number of people that would appear is
Instead, when Phyrra threw a stone, 9 people appear. So, for every stone, we have 9 new people.
Therefore, if Phyrra threw 68 stones, the number of people that would appear is
And so, we can now calculate the total number of people that appear after each had thrown 68 stones:
Answer:
17(x-2)
Step-by-step explanation:
Given the expression
17x - 34
We are to factorize it
Get their factors
17x = 17 * x
34 = 17 * 2
Since 17 is common to both factors, hence 17 is the GCF
17x - 34 = 17(x - 2)
Hence the equivalent expression is 17(x-2)
Answer:
(0,-7)
Step-by-step explanation:
In this question, we need to find an ordered pair of (x,y)
First we need to solve the equation for Y. It will be:
y-3=5(x-2)
y=5x-10 +3
y= 5x -7
Then, using the equation you can find the value of y using the value of x. If x= 0 the calculation will be
y= 5x-7
y= 5(0) - 7
y=-7
The ordered pair will be: (0,-7)
Answer:x=2, y=3
Step-by-step explanation:
solving this equation simultaneously
-9x - 2y=-12.............(1)
2x + 5y=-11.. ...........(2)
Using elimination method
Multiply equation 2 by 2 and equation 1 by 5
-45x -10y= -60...........(3)
4x + 10y=-22...............(4)
Subtracting equation 2 from 1
-41x + 0=-82
41x=82
x=82/41
X=2
To find y put x in equation 1
-9x - 2y= -12
-9(2)-2y=-12
-18-2y=-12
-2y=-12+18
-2y=6
Y= 6/2
Y=3
X=2, Y=3
