Is the triangle with side lengths of 18cm, 24cm and 30 cm a right triangle ?

kumpel [21]

If a, b and c are the lengths of a right triangle and c is the longest side, then:

$a^2+b^2=c^2$

We have a = 18cm, b = 24cm and c = 30cm. Substitute and check:

$L_s=18^2+24^2=324+576=900\\\\R_s=30^2=900\\\\L_s=R_s$

<h3>Answer: It's the right triangle.</h3>

Expression 3 + y and 2 (6+y) are equivalent?

Assoli18 [71]

Answer:

3+y and 12+2y

Step-by-step explanation:

I mean they aren't equivalent because if you do PEMDAS (parenthesis, exponents, multiply, divide, add, subtract) Then, you would do 2 times 6 because parenthesis, that equals 12 so the answer would be

3+y and 12+2y

Quadrilateral math is a parallelogram. the area of math is _____.

Semmy [17]

The area of a parallelogram can be obtained by multiplying the length of the base by the height. Although no diagram is given, let us assume values of the base and height that would yield one of the choices as answers. Let us say that parallelogram MATH has the following values:

base = 6 m
height = 11 m

Area = base * height = 6 * 11
Area = 66 m^2

Therefore, the answer is B.

On a drawing, the scale is 1 centimeter to 30 centimeters. Which of the following is not correct? actual length = 150 cm; drawin

Brrunno [24]

Answer:

drawing length = 7 cm; actual length = 200 cm

Step-by-step explanation:

The ratio is 1 cm in the drawing is 30 cm in actuality.

If the drawing is 5 cm, multiply by 5

5*1 to get the 5 cm drawing and 5*30 to 150 cm in actual length

5cm drawing = 150 cm actual

11cm drawing multiply by 11

11*1= 11 and 11*30 = 330 cm

11 cm drawing = 330 cm actual

7cm drawing multiply by 7

7*1= 7 and 7*30 = 210 cm

7 cm drawing = 210 cm actual

8cm drawing multiply by 8

The one that is not correct: drawing length = 7 cm; actual length = 200 cm

8*1= 8 and 8*30 = 240 cm

8 cm drawing = 240 cm actual
