Answer:
40
Step-by-step explanation:
To find the perimeter, first we need to find the side lengths.
If 100 cm is the area then we need to find what number squared is 100
10 x 10 = 100
So 10 is the side length. P= s + s + s +s
10 + 10 + 10 +10 = 40
4a - 3b
4(5) - 3(- 2)
20 + 6
26
26 is your answer.
Wait I don’t really get it but if you mean the result it is -5x^2 + 5 tho
Answer:
x= -8
Step-by-step explanation:
This can be done several ways:
The easiest is to factor out 12 from both sides so:
12(9-6x) = 12 (58-1)
12(9-6x) = 12 (57)
Cancel 12 from both sides so:
9-6x = 57, then...
-6x = 48
x= -8
P = 8 because 8+1=9 and 9•2=18
