We will expand the factored form of (x − 9)(x − 1) into the same form as x² − 10x + 9 to show they are equal.
Distribute and multipy out:
(x − 9)(x − 1)
x * x = x²
x * -1 = -x
x * -9 = -9x
-9 * -1 = 9
Add together:
x² + -x + -9x + 9
x² − 10x + 9
Use the Reflexive property:
x² − 10x + 9 = x² − 10x + 9 ✓
Yasss I think so but I bee help tooo
A. x=0, y=a*0+b=5, b=5
x=1, y=a*1+5=8, a=8-5, a=3
x=2, y=2*3+5=11
x=3, y=3*3+5=14
A is the answer

Wat is the question lol
Answer:
50 cm² and 56 cm²
Step-by-step explanation:
The area (A) is calculated as
A =
× d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )
(2)
A =
× (8 + 2) × (5 + 5)
= 0.5 × 10 × 10
= 5 × 10
= 50 cm²
(3)
A =
× (12 + 2) × (4 + 4)
= 0.5 × 14 × 8
= 7 × 8
= 56 cm²
