Answer:
No
Step-by-step explanation:
One way to solve is to algebraically find what d is and then solve using PEMDAS to see if both sides are equal. However, there is a faster way, this way is to remember the properties of equality. In this case, the subtraction property of equality is especially important. This property tells us that if you subtract the same thing from both sides of the equation then they are still equal. But, in this equation two different constants are being subtracted, 25 and 20, therefore the equation cannot be true.

The total price of Mr. Oliver's order is $189 including discount and tip.
Step-by-step explanation:
Given,
Bill of groceries = $175
Coupon 10% off
Amount of discount =
Amount of discount = $17.50
Bill after discount = 175 - 17.50 = $157.50
Tip = 20% of bill after discount
Amount of tip =
Amount of tip = $31.50
Bill after tip = 157.50+31.50 = $189

Step-by-step explanation:
Given
(x + 2)(x - 7) = 0 ← in standard form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 7 = 0 ⇒ x = 7
Thus the zeros are x = - 2 and x = 7
