Which equation shows one way to find the value of 45 × 4? 45 × 4 = (9 × 5) × (2 × 2) = (9 × 2) × (5 × 2) = 18 × 10 = ? 45 × 4 = (9 × 5) × (2 × 2) = (9 + 5) × (2 + 2) = 14 × 4 = ? 45 × 4 = (9 × 5) × (2 × 2) = (9 + 2) × (5 + 2) = 11 × 7 = ? 45 × 4 = (9 × 5) × (2 × 2) = (18 × 2) × (10 × 9) = 36 × 90 = ?

45 × 4 = (9 × 5) × (2 × 2) = (9 × 2) × (5 × 2) = 18 × 10 = ?

Step-by-step explanation:

Which equation shows one way to find the value of 45 × 4?

45 × 4

Splitting each number into factors of each other

45 = 9 × 5

4 = 2 × 2

45 × 4 = (9 × 5) × (2 × 2)

45 × 4 = (9 × 2) × (5 × 2)

45 × 4 = 18 × 10

Option A is the correct option

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
