AB = -2
CD = -1
BC = -3/-2
AD = -2/-3
The value of the expression (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵) will be 6.958 x 10⁻¹³. Then the correct option is C.
<h3>What is subtraction?</h3>
It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.
The expression is given below.
⇒ (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵)
Simplify the equation, then the value of the expression will be
⇒ (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵)
⇒ (7 x 10⁻¹³) − (0.042 x 10⁻¹³)
⇒ 6.958 x 10⁻¹³
The value of the expression (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵) will be 6.958 x 10⁻¹³. Then the correct option is C.

Answer:
It will take 7.8 hours to print designs on 1300 shirts
Step-by-step explanation:
We will use the ratio method to solve this question
∵ A machine prints designs on T-shirts
∵ It prints 500 shirts in 3 hours
∵ x is the number of hours to print 1300 shirts
→ By using the ratio method
→ shirts : hours
→ 500 : 3
→ 1300 : x
→ By using cross multiplication
∵ 500 × x = 1300 × 3
∴ 500x = 3900
→ Divide both sides by 500
∴ x = 7.8
∴ It will take 7.8 hours to print designs on 1300 shirts
