Answer:
These expressions are both correct because they are equivalent to each other.
5(4) + 7(4) = 20 + 28 = 48
(12 x 8)/2 = 96/2 = 48
Let me know if this helps!
Answer:
Step-by-step explanation:
BC = 15 cm
3x = 15
x = 15/3 = 5
AB =4x = 4*5 = 20 cm
Pythagorean theorem,
AC² = AB² + BC²
= 20² + 15 ²
= 400 + 225
= 625
AC = √625 = 25 cm
AC = 25 cm
Answer:
disagree because x should equal one
x=1
Step-by-step explanation:
5x times 4 =20
divide both sides by 5 times 4
x=1
