Answer:

question 1.   13) 1/2 ( 4a + 12) =

(13(1/2) ) (4a) + (13(1/2) ) (12) = 26a+78

question 2.    (14)(4)b2+3.5−2a+3.5b2−a

=56b2+3.5+−2a+3.5b2+−a

Combine Like Terms:

=56b2+3.5+−2a+3.5b2+−a

=(56b2+3.5b2)+(−2a+−a)+(3.5)

=59.5b2+−3a+3.5

A student is 5 feet, 2 inches tall. What is her height in meters?
Maurinko [17]
We know that 1 feet is 0.3m and that 1 inch = 0.0254 m
To get the result we have to multiply 5 feet by 0.3 and 2 inches by 0.0254 and add it.
5*0.3=1.5
2*0.0254=0.0508
Now adding
1.5+0.058=1.55m - its the answer

True or False? Def is a right triangle.
myrzilka [38]

Answer:

Step-by-step explanation:

We can determine if the triangle is a right triangle by using the Pythagorean theorem

a^2 +b^2 = c^2  where a and b are the legs and c is the hypotenuse

25^2 + 27^2 = 48^2

625+729=2304

1354 ≠2304

This is not true, so this is not a right triangle
