ANSWER
EXPLANATION
We want to simplify the expression,
Let us expand the bracket to obtain,
We now group the complex number parts and real number parts.
We simplify further to obtain,
This is in the form,
where
and
Ask: When will (4w-5)(7-w) equal zero?

Solve each of the 2 equations above
w = 5/4 , 7
Answer:
x = 1.5
Step-by-step explanation:
Since the axis of symmetry is between the 2 x intercepts, we can find it by finding the average of the x-coordinates of the 2 points.
(-7 + 10) / 2
3/2
= 1.5
So, the axis of symmetry is at x = 1.5
The right answer is Option A:
Step-by-step explanation:
Given expression is;
We will solve this expression for x, therefore,
Multiplying both sides by r
Subtracting t from both sides
Dividing both sides by 2
The right answer is Option A:

Answer:
Step-by-step explanation:
((8 x 10) x 3) + ((9 x 8)/2) x2 = (80 x 3) + (72/2) x 2
= 240 + (36 x 2)
= 240 + 72
= 312
