Answer:
13
Step-by-step explanation:
using c^2 = a^2 + b^2
whereas c is the length of the ladder
a is the top of the ladder
b is the distance from building
so c^2 = 12^2 + 5^2 = 144 + 25 = 169
c = 13
Line1: y = -x + 2
Line2: y = 2x - 1
Solution: (1,1)
Using PEMDAS, we know that we must solve what’s in the perentheses first so: 25/5 + 7 - (4x3) = 25/5 + 7-12. Next, we simplify 25/5 because that is division so now it is 5+7-12. Now you add 7 to 5 to get 12 and then subtract 12 so your answer is now zero.
