12 is the answer 6x2 basically
<u>w</u><u>=</u><u>-</u><u>1</u><u>.</u><u>5</u>
<u>w</u><u>=</u><u>2</u>
Answer:
Solution given:
again
keep square root alone
solve subtraction of 7-2
Squaring on both side
2w²-19w+31=5²-2*5*2w+4w²
take terms one side
2w²-19w+31-25+20w-4w²=0
-2w²+w+6=0
2w²-w-6=0
doing middle term factorisation
2w²-(4-3)w-6=0
2w²-4w+3w-6=0
take common from each two term
2w(w-2)+3(w-2)=0
(w-2)(2w+3)=0
either
w=2
or
W=-3/2=-1.5
4q
<span>We can
write the verbal expression of this algebraic or mathematical expression as simple
as four times a number. Since the unknown variable here is “q” and it is not
specified it doesn’t mean a specific letter q but just a representation of an
absent and unknown value of a number. Hence, these variables have a automated
value of 1 hence, q = 1 but unless the value of this variable is changed in
finding or filling this unknown it remains with the constant of 1.</span>
