Answer:

positve

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Since all the expressions are on a straight angle (equalling 180) combine the expressions to form on big expression that is equal to 180 and solve.

6x - 10 + 4x + 6 + 7x + 14 = 180

17x + 10 = 180

      - 10    -10

17x = 170

÷17    ÷17

x = 10

Answer:

Lemons: 4     12         36

Limes:    2      6           18

Step-by-step explanation:

For every 2 lemons, there is a lime, 4/2 = 2, so for the first one, 6*2 = 12, and the second, 36/2 = 18

The equivalent rations are 4:2, 12:6, and 36:18

Answer:

Step-by-step explanation:

Base x Height = Area

10x12=120 the area of the rectangle is 120

area of the triangle is 28

sorry but I don't know the trapezoid

The area of the rectangle is 120 cm².

The area of the triangle is 24 cm².

The area of the trapezoid is 144 cm².

An open, flat object with four straight sides and one pair of parallel sides is referred to as a trapezoid or trapezium.

A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases. The legs of a trapezium can also be parallel. The parallel sides may be vertical, horizontal, or angled.

The area of a trapezoid is (1/2)×(sum of the two parallel sides)×height.

We know, the area of a triangle is (1/2)×base×height and the area of a rectangle is (length×width).

Therefore, From the given information,

The area of the triangle is, (1/2)×4×12 = 24cm².

And the area of the rectangle is, (10×12) = 120 cm².

Therefore, The area of the trapezoid is,

= (24 + 120) cm².

= 144 cm².

Answer:

x=56

Step-by-step explanation:

because they are parallel lines, the angle 124 is the same measurement as the angle on the other side of the line with x. (look at the attachment, im bad at explaining with words lol)

then you do 180 - 124 (180 is the angle of a straight line) and you get x.

Answer:

Answer:

x = 48

Step-by-step explanation:

(x - 6)⁰ + ( 2x + 42)⁰ = 180⁰

x - 6⁰ + 2x + 42⁰ = 180⁰

x + 2x - 6⁰ + 42⁰ = 180⁰

3x + 36⁰ = 180⁰

3x + 36⁰ - 36⁰ = 180⁰ - 36⁰

3x = 144⁰

3x / 3 = 144⁰ / 3

x = 48
