This is a kite. We can split it into 2 equal triangles.

Length = 42.7 + 22.5 = 65.2cm
Height = 16.3 cm

Area of triangle = 1/2 x base x height

2 Area of triangles = 2( 1/2 x 65.2 x 16.3) = 1063 cm² (nearest cm)

Answer: 1063 cm² (Answer B)

According to the Rational Root Theorem, which function has the same set of potential rational roots as the function g(x) = 3x5 –

elena55 [62]

Answer:

Step-by-step explanation:

Given is an algebraic polynomial of degree 5.

$g(x) = 3x^5-2x^4+9x^3-x^2+12\\$

Here leading term is p=3 and constant term is q =12

Factors of p are ±1,±2,±3

Factors of q are $\frac{±1,±2,±3,±4,±6,±12} \\$

Possible forms of p/q will be the same for any other polynomial of degree 5 with leading term =3 and constant term = 12

Hence any other polynomial

$g(x) = 3x^5+ax^4+bx^3+cx^2+12$

will have same possible zeroes of p/q, when a,b,c are rational.

Hence any polynomial of this type would have the same possible rational roots.

Answer:

$x=10$

Step-by-step explanation:

we know that

If the lines m and n are parallel

then

$130\° = (8x+50)\°$ ----> by corresponding angles

solve for x

$8x=130-50\\8x=80\\x=10$

Amelia wants to paint three walls in her family room. Two walls are 26 feet long by 9 feet wide. The other wall is 18 feet long

sattari [20]

Given:
Wall 1 & 2 : 26 ft by 9 ft
Wall 3 : 18 ft by 9 ft

Area 1 : 26 ft x 9 ft = 234 ft²
Area 2 : 26 ft x 9 ft = 234 ft²
Area 3 : 18 ft x 9 ft = 162 ft²

Total Area : 234 ft² + 234 ft² + 162 ft² = 630 ft²

1 Gallon = 250 ft²

630 ft² ÷ 250 ft² per gallon = 2.52 gallons
