The answer is B. because (4-10) equals -6 and (4-4) equals 0. -6 times 0 is 0.
Answer:
x=6
Step-by-step explanation:
1 Add 44 to both sides.
2x=8+42x=8+4
2 Simplify 8+48+4 to 1212.
2x=122x=12
3 Divide both sides by 22.
x=\frac{12}{2}x=
2
12
4 Simplify \frac{12}{2}
2
12
to 66.
x=6x=6
The answer would be B 11 yards 1 foot
