Use the distributive property to write an equivalent expression without parentheses. 9 (a + 8) Check all that apply.

a-Distribute 9, by multiplication, to the variable, a, and to the constant, 8.

b-Write the two multiplications, 9(a) + 9(8)

c-The expression 9(a) is written as 9a.

d-The expression 9(8) equals 72.

e-The equivalent expression is 9a + 8.

f-The equivalent expression is 9a + 72.

Examine the paragraph proof. which theorem does it offer proof for? prove jnm – nmi according to the given information in the image. jk | hi while jnm and lnk are vertical angles. jnm and lnk are congruent by the vertical angles theorem. because lnk and nmi are corresponding angles, they are congruent according to the corresponding angles theorem. finally, jnm is congruent to nmi by the transitive property of equality alternate interior angles theorem gorresponding angle theorem vertical angle theorem o same side interior angles theorem
