Haha this one is the exactly why
Answer:
B. 3
Step-by-step explanation:
We can use secant theorem.
AX × BX = EX × DX
AX = 7 + 2 = 9
9 × 2 = (3 + x) × 3
18 = 9 + 3x
18 - 9 = 3x
9 = 3x
x = 9/3 = 3
The length of ED is 3 units.
Answer:
Discounted amount = $10
Sales price = $40
Step-by-step explanation:
Given:
Phone cost = $50
Discount rate = 20%
Find:
Discounted amount and sales price

Sales price = Phone cost - Discounted amount
Sales price = $50 - $10
Sales price = $40
Answer:
always
Step-by-step explanation:
this product can also be written as a^2 - ab - ab + b^2
which is a^2 - 2(ab) + b^2
a perfect square trinomials equation is
a^2 + 2(ab) + b^2
and this qualifies
