If you mean (x^2 -16), then x^2-16 = (x+4)*(x-4). This follows from the formula a^2 - -b^2=(a+b)*(a-b)
Triangles are congruent
so
4x + 1 = 13
4x = 12
x = 3
In case you need to find y
2x + y = 8x - 2y
2(3) + y = 8(3) - 2y
6 + y = 24 - 2y
3y = 18
y = 6
<span>Number line refers to a mathematical process of
solving the equation with the use of lines.
=> 235 + 123
Starting from 0 you count 1 up to 235. Then starting from 235 you additionally
count another 123.
Then from zero start counting the total number to the line you stopped when
adding 123 to 235.
This simply equals to
=> 235 + 123
=> 358.
Pls. see attached image for illustration of number line.</span>Answer here
By rolling two dices, you can have a result in 36 ways because every die has 6 sides. And if we are going to use a formula, it would be 6*6. But since the way which would have the result of 12 is an exemption, there would only now have 35 ways.
Y = -3
T = -4
7x - 14
X = 4
