Answer: x=7/4 or x=7
Step-by-step explanation:
step 1: Factor left side of equation.
(4x−7)(x−7)=0
Step 2: Set factors equal to 0.
4x−7=0 or x−7=0
x=7/4 or x=7
Answer:
8
Step-by-step explanation:
(10)^2 - (6)^2 = 64
Square root 64 = 8
Ok first one when you are dealing with two step equations you need to cancel out the -6 so add 6 to both side so now you have 28 and divide that by 4 because you need to cancel out the 4
4x-6=22
+6=+6
4x=28
4x/4=28/4
X=7
7 1/5 = 7 + 1/5
= 7/1 + 1/5
= (7/1 * 5/5) + 1/5
= 35/5 + 1/5
= 36/5
= 36 ÷ 5
= 7.2
