Answer:
√23 = a
Step-by-step explanation:
/ab/²= /ac/²+/bc/² (Pythagoras theorem)
12² = a² +11²
144 = a² + 121
144 - 121 = a²
23 = a²
√23 = a
The answer is (3,7) I hope this helps!!!
Answer:
EQUATION IS GIVEN BELOW.
Step-by-step explanation:
let the number be 'x'
now,
x+12 =36
or, x=36-12
therefore,x=24
Use the FOIL method to multiply these terms. Multiply the first, outside, inside, and last terms:
(5x - 4)(2x - 5)
(5x)(2x) + (5x)(-5) + (-4)(2x) + (-4)(-5)
10x² - 25x - 8x + 20
10x² - 33x + 20
The area of the rectangle should be 10x² - 33x + 20.
Answer is C:9
12^9/12^5 = 12^4
