(4x2 – 4x – 7)(x + 3)
(4x2 – 4x – 7)(x) + (4x2 – 4x – 7)(3)
4x2(x) – 4x(x) – 7(x) + 4x2(3) – 4x(3) – 7(3)
4x3 – 4x2 – 7x + 12x2 – 12x – 21
4x3 – 4x2 + 12x2 – 7x – 12x – 21
4x3 + 8x2 – 19x – 21
G(3) means that x = 3. Plug in 3 wherever x is present.
5(3) - 2 = 15 - 2 = 13
The answer is 13.
I think there are no solutions - firstly, you can't add two numbers and get one solution, and add the same two numbers up again and get a different solution!
also, if you plot the two lines on a graph they never intersect, showing there are no values of x or y that satisfy both equations.
Answer:
x= 35
Step-by-step explanation:
supposing we are finding x, we know that the line in the middle is the dimeter. so we know its a semicircle with an arc of 180 degrees. 180-110=70 divide that by two to get x which is 35.
I think it is 11 cm
I really hope u get it right
