Answer: 1: 5(3x+4)
2: 6(x2+4x−3)
3: 5x(4x2−3x+2)
4: 4n2(4n2-3)
Step-by-step explanation:
Z=kx, 30=8k, so k=30/8=15/4 and z=15x/4, so when x=4, z=15.
Its A. the side lengths squared equal the hypotenuse squared.
With base-ten blocks ,there would be the 3 units, 1 tens block , and five hundreds cubes
Tip:
draw a diagonal and compare triangles ;)
