Answer: 54 in.

Step-by-step explanation: So, the problem does something a little sneaky, and that is they ask for the TOTAL amount of wood needed for triangle DFG. And to find that, we simply have to multiply side AC by 3 to get side DG. We do this because triangle ABC is 3 times as small as triangle DFG. Then, add your side DG that you just got, (21) to side FG and FD to get the total amount of wood needed, 54 in.

A) Find a number $0\leq x<14$ that solves the congruence $9x \equiv 9 \pmod{14}$.

Rus_ich [418]

A) Find a number $0\leq x$ that solves the congruence $9x \equiv 9 \pmod{14}$ .

 $9x \equiv 9 \pmod{14}$ means that 9x-9 is a multiple of 14,

that is 9(x-1) is a multiple of 14. A clear solution in the set is x=1

b) Find a number $0\leq x$ that solves the congruence $3x \equiv 4 \pmod{5}$ .

 $3x \equiv 4 \pmod{5}$ means that 3x-4 is a multiple of 5,

x∈{0, 1, 2, 3, 4} , so for these values 3x-4 becomes {-4, -1, 2, 5, 8}.

so x= 3 

c)Find a number $0\leq x$ that solves the congruence $999x \equiv 998 \pmod{1000}$ .

 $999x \equiv 998 \pmod{1000}$ means that 999x-998 is a multiple of 1,000

we can check that for x=2, 999*2-998=1,998-998=1,000

d)Find a number $0\leq x$ that solves the congruence $4x \equiv 17 \pmod{21}$

$4x \equiv 17 \pmod{21}$ means that 4x-17 is a multiple of 21,

fro x=7, 4x=28 and so 4x-17=28-17=21 is a multiple of 21.
