Answer:
5²+1×2 - 4(4) = 11
Step-by-step explanation:
up top when it says a = 4
and b = 5 that's means b and a are those numbers. 
then while 4 is touching a that means to multiply. And the 2 up top of b means 5×5, then do order of operations to find the answer. If you dont you'll get it WRONG.
Order of operations is this
Parentheses 
Exponents
Multiplication 
Division 
Addition
Subtraction

w = 4
L = 7
Step-by-step explanation:
L = length of rectangle 
w = width of rectangle 
L = 3 + w
A = 28 
A = L*w
=(3+w) * w 
28 = 3w + w^2
w^2 + 3w - 28 = 0
w^2 + 7w - 4w - 28 = 0
w ( w + 7 ) - 4 ( w + 7 ) =0
( w - 4 ) ( w + 7 ) = 0
w = 4. and w = -7
take the postive value, w = 4
therefore L= 3+4 = 7
 
        
             
        
        
        
Answer:
A
Step-by-step explanation:
I believe it is A because for perpendicular lines the slope must be the reciprocal and have the opposite sign. The y-intercept 2 matches the coordinates (-2, 2). The second number, 2, is the y coordinate.
 
        
             
        
        
        
Answer: 1/3
Step-by-step explanation: The probability is given by the number of times the event could happen (in this case get an "e"), over the number of all the possibilities (in this case, the six letters of the word)
Therefore, probability
