Answer:
x=25
Step-by-step explanation:
24²+7²=625
√625= 25
You can factorize this square trinomial in the next way
x∧2-2x-80= x∧2-10x+8x-80= x(x-10)+8(x-10)= (x-10) (x+8)
The correct answer is (x-10) (x+8)
Good luck!!!
Answer:
0.76=x
Step-by-step explanation:
to solve this you want to get x by itself on one side.
0.75x+4=6x
we'll move 0.75x over to the other side.
0.75x-0.75x+4=6x-0.75x
now we simplify.
4=5.25x
now we divide both sides by 5.25x.
4/5.25=5.25x/5.25
≈0.76=x
Of I don’t know sorry about that
