Answer:
A) 4x^2+20x+25=(2x)^2+2*(2x)*5+5^2=(2x+5)^2
Area=(side)^2, side=sqrt(area)=sqrt((2x+5)^2)=2x+5
B) 4x^2-9y^2=(2x-3y)(2x+3y), these are the dimensions of the rectangle
The answer is if 5(3x - 7 ) = 20 than 6x - 8 is 2(3x - 4) You get this answer when you factor it.
Standard form : Ax + By = C
y - 4 = 0
y = 4...this is a horizontal line and a horizontal line has a 0 slope
so in standard form, ur equation is : 0x + y = 4
16 oz
2 Tbs = 1 oz
2 Tbs = 1 oz
2 Tbs = 1 oz
2 Tbs = 1 oz
2 Tbs = 1 oz
2 Tbs = 1 oz
2 Tbs = 1 oz
2 Tbs = 1 oz
Continue this 16 times total
So 2 Tbs x 16 oz = 32 Tbs
