Answer:
B
Step-by-step explanation:
ac =5x
cb=7x
(5x×5x)+ (5 +7)^2 = 7x^2
25x^2+144=49x^2
x=kök 6
ac =5kok 6
(5kok6)×12÷2= 30 kök 6
Answer:
(3, 0) and (−1, −8)
Equation's:
<h3>
Substitute equation 2 into 1</h3>
2x − (x² − 9) = 6
2x - x² + 9 = 6
-x² + 2x + 9 - 6 = 0
-x² + 2x + 3 = 0
x² - 2x - 3 = 0
x² - 3x + x - 3 = 0
x(x - 3) + 1(x - 3) = 0
(x + 1)(x - 3) = 0
x = -1, x = 3
<h3>Find values for y</h3>
If x = -1, then y = (-1)² - 9 = -8
If x = 3, then y = (3)² - 9 = 0
<h3>Solution Set:</h3>
(x, y) = (-1, -8), (3, 0)

Answer:
Her total loss was £25
Step-by-step explanation:
Here, we want to get the value of total loss
What we have to do here is to subtract the amount made from the running cost
From the question, we have the amount made as;
£1.40 * 50 = £70
So we have the loss as,
70-95 = -£25
