What algebraic expression must be added to the sum of 3x2 +4x+8 and 2x2−6x+3 to give 9x2−2x−5 as the result?
vesna_86 [32]

Answer:

4x^2-16

Step-by-step explanation:

-This is an addition/subtraction problem.

#We subtract the sum of the first two expression from the third expression:

\#Add \ first \ two\\\\=3x^2 +4x+8 +2x^2-6x+3\\\\=5x^2-2x+11\\\\\# Subtract\ from \ the \ third\\=(9x^2-2x-5)-(5x^2-2x+11)\\\\=9x^2-2x-5-5x^2+2x-11\\\\=4x^2-16

Hence, the expression 4x^2-16 must be added to the first two.

1) IF the area of the frame was 64inches², what would be 2 possible sets of dimensions that could be used to make a frame with t
neonofarm [45]
There are infinite possibilities for this answer, let's see how:
Assuming the frame is rectangular, and it has 64 square inches, then the multiplication of the height (H) and width (W) is 64.
So H*W=64, therefore H=64/W
Any pair of numbers that fits this equation will be a possible answer.
A few examples:
H=1; W=64
H=2; W=32
H=1,23456; W= 51,840338
H=4; W=16
H=8; W=8
etc.

So, for example, one set can be 8x8 inches
another set can be 4x16 inches

if the frame were to have 5 inches and 7 inches, since 1 inch correponds to 2.5ft, then we simply must multiply the values in inches per 2.5 to get the values in feet, then it would correspond to
5*2.5=12.5 ft  and   7*2.5=17.5 ft
