Harvey is solving an equation. His work is shown below. 5x+(5x+9)=5
(5x+5x)+9=5
10x+9=5
Which statement describes the procedure Harvey used in his work and which property justifies the produce? A.) Harvey regrouped the terms to add 5x and 5x. This procedure is justified by the associative property B.) Harvey regrouped the terms to add 5x and 9. This procedure is justified by the commutative property C.) Harvey regrouped the terms to multiply 5x and 5x. This procedure is justified by the commutative property D.) Harvey regrouped the terms to multiply 5x and 5x by 9. This procedure is justified by the associative property.

yess

step-by-step explanation:

idk whyy this is happening, i cant even read my notification bc i keep getting errors

~coco

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
