A square is a quadrilateral that has 4 angles that is 90 degrees.
2/10, or 5/25 can i get brainliest
i just multiplied the top n bottom number by the same number
Answer:
Simplifed (X-5)(x^2+4x-2) = x^3 − x^2 − 22x + 10
Step-by-step explanation:
Expand ( x − 5 ) ( x^2 + 4x − 2 ) by multiplying each term in the first expression by each term in the second expression.
x ⋅ x^2 + x (4x) + x ⋅ −2 −5x^2 − 5 (4x) −5 ⋅ −2
Simplify terms.
x^3 − x^2 − 22x + 10
I hope this helps.
perimeter of a triangle ABC
Perimeter of a Triangle
= AB + BC + CA
= 10cm + 8cm + 12cm,
(add the length of each side of the triangle).
= 30cm
Perimeter of the triangle = Sum of the sides.
20 quarters
5x 4 =20
hope it helped bye
