Set the function equal to zero and solve for x. 0=x^2+4x+12 factors to 0=(x-2)(x+6) which gives you intercepts of x=2 or -6.
Answer:
B. 2(3w-4)+2w=54
Step-by-step explanation:
L = 3 W - 4
2L + 2W = 54
2 x (3W - 4) + 2W = 54
Answer:
This answer is 42
Step-by-step explanation:
42 - 24 = 18
Answer:
4
Step-by-step explanation:
the third angle of the inner triangle is defined by using the rule that the sum of all angles in a triangle must be 180 degrees. let's call this angle a
180 = 48 + 16x + a
132 - 16x = a
and then we know that both angles, 28x and a together must also be 180, as they are complementing each other to cover the whole top of the base line.
so,
28x + 132 - 16x = 180
12x = 48
x = 4
