Answer:

45

Step-by-step explanation:

the formula is (P x slant height over 2) + B

P = perimeter of the base

B = area of the base

P = 3+3+3+3  P=12

B=3x3  B = 9

12 x 6 = 72    72 divided by 2 = 36    36 + 9 = 45

the surface area of your triangle is 45 cm squared

Paul [167]

Answer:

B) , C)

Step-by-step explanation:

Assuming that you are multiplying each of the numbers for each given answer.

Look at the amount of negative signs provided. Odd amounts of negative will always guarantee a product of a negative answer. Even amounts of negative will always guarantee a product of a positive answer.

In this case, C. -4 , -4 , -4 , 4 & B. -4 , -4, -4, 4 are your answers, for both only have 3 negative signs, which would make a negative answer.

Answer:

side c = 150 feet of flowers

Area = 5400 feet squared

concert question:

The converse of the Pythagorean theorem can help you determine whether the roped off area is in the shape of a right triangle because you use the side lengths of each square and enter them into the equation, and if the equation is true, then it is a right triangle

Concession stand question:

The school banner can fit across the length of the concession stand

the following information is missing

The length if the sides: c is 50 feet long, b is 40 foot long, and a is 30-foot long.

The distance between the two red stars of the picture makes the hypotenuse of a right triangle, where two sides of length a (30 ft) are the legs. From Pythagorean theorem, diagonal of square A is:

diagonal² = 30² + 30²

diagonal = √1800  = 42.43 ft

which is longer than the banner.

Blueprint question:

No, diagonal of square C is 70.71ft

Why does it say your phone is being attacked and then said something with 26 when I go on a website is it lying or do I have a v
irina [24]

Answer:

If you go to a website that has a red (or orange) triangle with an exclamation mark next to the link, it's an untrusted site. The things you list (your phone is being attacked and then said something with 26..) are likely to be scam ads (probably viruses). Therefore,  I do not recommend you to click the ads or enter that site again.
