90=20+70 use the distributive property and the GCF OF 20 and 70 to write another related expression for 90 could you write anoth

juin [17]

90 = 20 + 70.....GCF of 20 and 70 is 10
90 = 10(2 + 7) <==

can u write another expression using a different common factor...yes
90 = 20 + 70.....common factor is 5
90 = 5(4 + 14) <==
