Using factorization method;
x²+13x+40=0
x²+13+40
Find two numbers that you can add together to give the co-efficient of variable x. (I.e 13 for this question). Also, you'll find two numbers that you can multiply with each other to give you the whole number as an answer. (I.e 40 in this question). The two numbers must be the same (i.e the two numbers that will be added to give the co-efficient of x and the two numbers that will be multiplied to give the whole number must be the same two).
The two numbers are +5 and +8
The equation will therefore be = x²+5x+8x+40
You'll then factorize (I.e use a common factor of both values to bracket them)
x(x+5)+8(x+5)
(x+8)(x+5)
x is therefore (x+8=0) or (x+5=0)
x=(x=0-8) or (x=0-5)
x= -8 or x= -5
Greetings ! Your Answer Is Below.
Answer;
1. m = 16
2. x = -z + 34 or z = -x + 34
3. p = 49
Step-by-step explanation;
1. m + 13 - 13 = 29 - 13 | Subtract 13 from both sides ( m = 16 )
2. - z + 34 | Add -z to both of the sides ( x = - z + 34 )
Or - x + 34 | Add -x to both of the sides ( z = - x + 34 )
3. 136 - 87 = 49 | Subtract 87 from both sides ( p = 49 )

Answer:
6(x+3)
Step-by-step explanation:
6x+18
6*x + 3*6
Factor out a 6
6(x+3)
<span>In this expression, the variable ’t’ stands in for any possible value of seconds. Therefore, since you know how long it takes the object to fall in seconds, you can put this into the expression. 16 x (4^2) = 256. The distance is 256ft.</span>
