Answer:
Its either A or C
Step-by-step explanation:
(2x-3)(x+5)
Use foil to simplify, First multiply together the first terms of the pairs, then the outer terms, the middle terms, and finally the last terms. Then combine like terms.
2x^2+10x-3x-15 equals 2x^2+7x-15
Answer:
D
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 6, - 8), thus
(x + 6)² + (y + 8)² = r²
The radius is the distance from the centre to a point on the circle
Calculate r using the distance formula
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 6, - 8) and (x₂, y₂ ) = (0, 0)
r =
=
=
= 10
Hence
(x + 6)² + (y + 8)² = 100 → D
Answer:
$462.7
Step-by-step explanation:
15% commission on $54
= $8.1
he sell 27 boards so
8.1 × 27=$218.7
so
$245.00+$218.7=$463.7
