1. True or False: All quadrilaterals with the same side lengths will be identical copies. 2. True or False: All triangles with the same side lengths will be identical copies.

3. Select which set of three side lengths will always make a triangle (a, b, or c):

4, 5, 6

7, 6, 12

5, 11, 13

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
