actually box 3 is correct.
because their radiuses are easy to find
but the tangent line is x=-4 or x=4
Answer:
1. Square, 10in x 8in, 160in^2
2. Each surface has an area of 80in^2
Step-by-step explanation:
1. Rectangle is the shape of each cut surface which is 10in by 8 in. Since the block was already painted with glitter, she needs to paint both sides of the cut surface only, 2*8in * 10in = 160in^2.
2. Each cut will have a surface area of 10in * 8in = 80in^2

Answer:
4x²+13x+9
iwill give you good method to simplify this
firstable take the 4 from x² and multiply it by 9
x²+13x+36
we find this equation
so the values is 4 and 9 because 4+9=13
4×9=36
(x+ )×(x+ )
first we take 9 and devide it by 4
9/4 the four for the x and the nine is number
so its will be
(4x+9)×(x+ )
same thing with 4 devide by 4 so the value is 1
so its will be like this
(4x+9)×(x+1) and this is the answer hopefully you understand my explain with my English
