Answer:

d. 2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

45a−25+7a=79

45a+−25+7a=79

(45a+7a)+(−25)=79(Combine Like Terms)

52a+−25=79

52a−25=79

Step 2: Add 25 to both sides.

52a−25+25=79+25

52a=104

Step 3: Divide both sides by 52.

52a

9514 1404 393

Answer:

  (x -7)(7x +4)

Step-by-step explanation:

The term -45x can be rewritten using factors of (7)(-28) that have a total of -45. Those factors would be ...

  (7)(-28) = (4)(-49)

7x^2 +4x -49x -28 = x(7x +4) -7(7x +4) = (x -7)(7x +4)

13) Is it possible to construct a triangle with base angles 180 and 70° and perimeter 14 cm?<br>​
Nataliya [291]
No.
The three angles of a triangle need to add up to 180 degrees, this means no one angle can be 180 degrees.
