Answer: y>14/3
Step-by-step explanation:
Substituting -3 for x, we have: (-3)^2-3*-3-7. This simplifies to 9+9-7, or 11.
Since the triangles are similar, all sides are proportional by the same scale factor.
The relationship between the bases 32 and 8 is 4 (32/8 = 4). This means that the smaller triangle need to be multiplied by a scale factor 4 to result in the bigger triangle.
This means that 4x + 12 is 4 times greater than 15.
The equation to solve for x can be written as:
4x + 12 = 4*15
Now just solve for x as u normally would
4x + 12 = 60
(Subtract twelve from both sides)
4x = 48
(Divide both sides by 4 to isolate x)
x = 12
I hope this somewhat helped :)
Was my explanation clear enough?
Yes, a negative times a negative will be postive and a positive with a positive will remain positive. but negative times positive will be negative, doesnt matter with integer is higher
