So use undistributive properyt]
ab+ac=a(b+c)
so factor 24a dadn 28 to find 'a' the common factor
24=2 times 2 times 2 times 3 tiems a
28=2 times 2 times 7
common one is 2 itmes 2=4
a=4
4(2 times3 times a)+4(7)=4(6a)+4(7)=4(6a+7)
"Calculate the square root of 10 (√ 10) to 4 decimal places.<span>Find the perfect square number closer to 10. 32 = 9 and 42 = 16, so take 3.Divide 10 by 3. 10÷3 = 3.33 (you can round off the answer)Average 3.33 and 3. ( 3.33 + 3)÷2 = 3.1667."

Answer:
Step-by-step explanation:
5x+14<4 or -2(x-8)<-2
-14 -14 -2x+16<-2
5x<-10 -16 -16
÷5 ÷5 -2x<-18
x<-2 ÷-2 ÷-2
x>9 (sign changes because you divide by a negative number)
x<-2 or x>9
