Which expression is equivalent to 4a + 10? 4(a + 5) 2(2a + 8) 4(a + 8) 2(2a + 5)

One way is to just multply them out but the easier way is to undistribute to see the answer

so
remember distributive property
a(b+c)=ab+ac

4a+10 is obvously a product
the common factor is 2 so
4a+10=2(2a)+2(5)
undistribute 2
2(2a)+2(5)=2(2a+5)
reverse distribute

answer is last option

Y=-2x-6 is the answer

7.1 is in between -8 and -7 because -7. 1 is equal to -7. 10 and that number is 10 numbers away from the number 7. ur welcome!
