Answer:
Area of trapezium = 1/2 * h (a+b)
here, 480= 1/2 *15*(20+b)
(20+b)=960/15
or, b=64-20
therefore, b= 44
.....
Hope u got it...xd
Step-by-step explanation:
(x+5)^2 = 2( 5x-3)
x^2+25=10x-6
x^2-10x+25+6= 0
x^2-10x+31=0
a=1, b
False because if the number was positive the opposite of that would be negative
I think the answer is 1/3 because you can simplify 4/12 into 2/6 and that can also be simplify into 1/3. Sorry if I am wrong let me know if i'm right
