Given only a compass and straightedge Greeks believed that many constructions were impossible to complete true or false

answer is  

a.

7 in. x 11 in.

hope you get this right.

the answer is 3.54 g/cm^3

step-by-step explanation:

d=mass/volume therefore d= 46/13 which is a simple division equation.

-2.19

step-by-step explanation:

i think

josh is incorrect

x= 7 and x= -1

step 2 is wrong and honestly first step is not needed, you just need to figure out the factors

i know its wrong because if you plug in the solutions josh found, they do not work (in the original equation)

x^2 -6x -7 = 0

(x-7) (x+1) = 0

x-7=0 x+1=0

x= 7 x= -1
