Step-by-step explanation:
Answer:
The coefficients are 2 and -3
The exponents are 5 and 1
Step-by-step explanation:
Given
Required
The coefficient and exponent
First, identify the terms.
The terms are: 
and 
The coefficient are the numbers written before the variables
The exponents are the power of the variables

For
The figure is a parallelogram so the facing sides have equal size which means :
DE = GF & DG = EF
-------------------------------------------------------------
DE = 3x - 1 , GF = 2x + 11
DE = GF ==》 3x - 1 = 2x + 11
subtract sides minus 2x
==》- 2x + 3x - 1 = - 2x + 2x + 11
collect like terms
==》 x - 1 = 11
add sides 1
==》 x - 1 + 1 = 11 + 1
==》 x = 12
-------------------------------------------------------------
As we found : DG = EF
DG = 2x - 3 So EF = 2x - 3
To find the size of EF, we need to put the value of x (which we found above) instead x.
EF = 2 × ( 12 ) - 3 ==》 EF = 24 - 3
==》 EF = 21
And we're done...
So the length will be 18^2-4^2 all rooted. 18 square is 324 and 4 square is 16 and 324-16 is 308 so the answer will be the root of 308 or 2 root 77, at least that is what I think.
