Answer:
c=5
Step-by-step explanation:
using pythagorean theorem, 3 squared plus 4 squared is 25. by finding square root of 25, you get 5
Answer:
3m
Step-by-step explanation:
we know that u know but ok
there are 100 cm in one meter .
this means 300 centimeters would be divided by 100.
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
It is 36
Bcuz 3X6=18
And 18X2=36
Hope i helped ^_^
