Answer:
Step-by-step explanation:
Answer choice C would be correct since both sides are increasing at a set rate, x is increasing by one while y is increasing by 2 every time. Hope this helps :)
We'll have this following figure drawn in the picture. Since we have an isosceles trapezoid, the diagonals are congruent. According to the conditions of the problem, these diagonals are perpendicular and then we can claim that we'll have right-isosceles triangles in this case. Indeed, ∠OBC = ∠FBD = 45°. Then, in the triangle BFD. BF=FD=23. It means the height is 23 cm. Obtaining this fact, we can easily calculate the area.
Step-by-step Answer:
Step 1:
Extract factor(s) common to all terms.
In this case, the HCF is 3, so the expression is written
-12x^2+45x+12 = -3(4x^2-15x-4)
The negative sign was also exrracted to give a positive leading coefficient, which is easier to work with.
Step 2, group the coefficient in such a way that there is a common factor.
Leaving the factor -4 for the moment, and concentrate on the coefficients in parentheses, write the original expression as
4x^2 - 15x -4
= 4x^2 -16x
+ x -4
= 4x*(x-4) + 1*(x-4)
extract (x-4) as a common factor
= (x-4)(4x+1)
Step 3:
Combine all the factors to get
-3(x-4)(4x+1)
=3(4-x)(4x+1)
as the complete factoring of the given expression.
