Answer:

Step-by-step explanation:
Given : 
Solution:



Thus , 
Thus the solution is irrational since square root 7 does not have a perfect square and equal to 6+2square root of 14
42 divided by 7 =6 then u times 5 and 6 together . Then times 2 by 6 together so the answer is 30:12
Answer:
associative prop
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. P = (width + lengh) * 2 = (23 + 10) * 2 = 33 * 2 = 66
A = width * lengh = 23 * 10 = 230
2. width = 7
P = (width + lengh) * 2 = ( 7 + 9) * 2 = 16 * 2 = 32
Answer:
1. w = 15
2. b = 4.8
3. s = 9.7
4. p =15
5. m = -3.2
Step-by-step explanation:
1.w + 10 = 25
we have to find the value of w, so moving 10 from left side to right side
w= 25 - 10
w = 15
2. 7.2 + b = 12
we have to find the value of w, so moving 7.2 from left side to right side
b= 12 - 7.2
b= 4.8
3. 5.3 + s = 15
s= 15 - 5.3
s= 9.7
4.p + (-25) = -10
p-25 = -10
p= -10 + 25
p= 15
3. m + (-1.6) = -4.8
m - 1.6 = -4.8
m = -4.8 + 1.6
m= -3.2
