Answer:
x=5 y=1
Step-by-step explanation:
Answer:
u = 1
Step-by-step explanation:
First, we can use inverse operations to help.
27 + 9u = 36
Next, we can start replacing u with numbers to find which number fits in u.
27 + 9(1) = 36
27 + 9(2) ≠ 36
27 + 9(3) ≠ 36
Now, we know that u = 1
Answer:
Step-by-step explanation:
<u>Area formula:</u>
<u>The height is:</u>
- h = (x + 2)sin 45° = √2(x + 2)/2
<u>Substitute the area value an set an equation:</u>
- 4√2 = (2x - 3)√2(x + 2)/2
- (2x - 3)(x + 2) = 8
- 2x² + x - 6 = 8
- 2x² + x - 14 = 0
- D = 1 + 4*2*14 = 113
- x = (-1 + √113)/4 = 2.41 (rounded)
Note. the second root ignored as negative
