Answer:
Step-by-step explanation:
__
The factoring of the difference of squares is applicable:
a^2 -b^2 = (a -b)(a +b)
The GCF of 6, 42, and 12 is:
6.
Answer:
x=-6
Step-by-step explanation:
The axis of symmetry is the lowest (or highest) point. It is the line where it becomes the mirror image.
Looking at the graph, this is the line x=-6
x = -6
Answer:
constant term is -3, the leading term is 3x^3, the coefficient is 3.
Step-by-step explanation:
If the width is Wthen the length is 2W-5 W(2W-5)=422W2-5W = 422W2-5W-42 = 0 Factor by grouping or do the quadratic equation.Multiply the coefficient of the squared term.. 2..by the constant ..-42.. 2(-42)=-84Factors of -84 that add to the coefficient..-5.. ofthe W term are 7(-12)Replace the -5W with -12W + 7W 2W2-12W+7W-42 = 02W(W-6) + 7(W-6)=0(2W+7)(W-6)=0
Either: 2W+7 = 0 or W-6 = 0 2W = -7 W = 6 cm W = -7/2 cm
Since W will not be a negative, our width is 6cmThe length is 2W-5 = 2(6)-5=12-5 = 7 cm
