Keelie has a triangular-shaped card. the lengths of its sides are 2.7 cm, 3.6 cm, and 4.5 cm. is the card a right triangle?

Yes it is the right angle triangle

Step-by-step explanation:

In right angle triangle hypotenuse is equal to sum of perpendicular and base

(H) ^2 = P ^2 + B ^2

(4.5) ^2 = (2.7) ^2 +(3.6) ^2

20.25 =  7.29 +12.96

20.25 = 20.25

Hence, it is right angle triangle .

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.
