Multiply 3x9 and it gives u 27
And -3 plus -9 equal -12
Answer:
20
Step-by-step explanation:
you've got to do the inside parenthesis first then multiple with 3 and finally add 8
Line 3 is where the error begins. 12^2 is not equal to 24, it is equal to 144. Same for 18^2.
Answer:
468 = hypotenuse^2
Hypotenuse= square root of 468
Area of a triangle: A= 1/2(base)(hieght)
base=x
height= 6(base)+1= 6x+1
13= 1/2 × (x)(6x+1)
(get rid of 1/2 by multiplying each side by 2)
26= (x)(6x+1)
26= (x × 6x)= 6x² (x × (+1))= x
26= 6x² + x
0= 6x²+x-26
Are either of those the answers? If not, list the options and I will be able to tell you which one is correct. Hope this helped!
