Answer:
To find the value of a, we can expand the expression (5a + 6) (7a) (5a+6)(7a) and then solve for a.
First, let's expand the expression: ( 5a + 6 ) ( 7a ) = 5a ⋅ 7a + 6 ⋅ 7 � (5a+6)(7a)=5a⋅7a+6⋅7a = 35a 2 + 42a =35a 2 +42a
Now, we need to find the value of a for which this expression holds true. Since we're only given the expression, not an equation or equality, we can't solve for a definitively without further information or context. If this expression equals another expression or value, we could then solve for a by setting the two expressions equal to each other and solving for a. But as it stands, without additional information, we can't determine a specific value for a.
