Pl plz this ? is realy hard simplify the expression 7(a−3+4b).

7(a−3+4b)

distribute

7a-7*3+7*4b

7a-21+28b

Use the distributive property to multiply the 7 by each term inside the parentheses.

7(a - 3 + 4b) =

= 7 * a - 7 * 3 + 7 * 4b

= 7a - 21 + 28b

7a - 21 + 28b

yes   because as the functions are graphed they eventually will intersect unless otherwise

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
