Answer:
21x-28
Step-by-step explanation:
you multiply 7 by 3 and 7 by 4 and bring down the x and subtraction sign
The distributive property: <em>a(b - c) = ab - ac</em>
7(3x - 4) = (7)(3x) - (7)(4) = 21x - 28
Hypotenuse² = perpendicular² + base²
H² = 20²+21²
H²= 400+441 = 841
H = √841
H = 29 cm
3/5 cups of fluid
2 1/2 / 6 = 3/5
Hopefully that helps.
