Hello there!
x² + x = 7/4
x² + - 7/4 = 0
Now we gonna use the quadratic formula to find x
a= 1
b=1
c = -1.75
x = -b+/-√b² -4ac all of them divide by 2a
x = -(1)+/-√(1)² - (4)(1)(-1.75) all of them divide by 2(1)
x= -1+/-√8 all of them divide by 2
x = -1/2 + √2 or x = -1/2 - √2
The correct option is option C
I hope that helps!
Answer:
Step-by-step explanation:
we know that
The perimeter of the rectangular lot is
----> equation A
where
AB is the length
BC is the width
we have
---> equation B
----> equation C
substitute equation B and equation C in equation A
solve for BC
<em>Find the value of AB</em>

Answer:
Tax=$0.91
Step-by-step explanation:
Tax=$12.99(.07)=$0.9093
Tax=$0.91
<span>Hence
2L + C = 1.4
-2L - 6C = -3.4
Add (This will eliminate 'L' )
-5C = -2.0
5C = 2.0
C = 0.4 = £0.40p
2L + 0.4 = 1.40
2L = 1.40 - 0.40 = 1.00
L = 0.50 = £0.50p.
Hence a lemonade (L) costs £0.50p & a Crisps (C) costs £0.40p.</span>
