X^2+10x+16=0
First, you find factors of 16.
1 x 16
2 x 8
4 x 4
Next, you find which of the factor pairs adds up to 10 (from the 10x). In this case, 2 x 8 because 2 times 8 is 16 and 2 plus 8 is 10.
Then, the equation will be written out as: (x+2) (x+8). Take those two equations and set them equal to 0, and then solve.
x+2=0
-2 -2
x=-2
x+8=0
-8 -8
x=-8
So, your answers are x=-2 and x=-8. You can check by plugging in those two numbers as x.
Answer: D
Step-by-step explanation:
(3/8) / (5/9) is the same as multiplying (3/8) by (9/5) which is 27/40. I'm not sure if there's an error between C and D because those are both the same answer since dividing a negative number by a negative number gives you a positive number.
I think C was supposed to be -27/40 so D is the correct answer since it's positive.
Step-by-step explanation:
Both squares are 50% = 100% in total.
1 square= 50%
1/2 of a square= 25%
50+25= 75% I think i'm pretty sure that's the answer.
Given:
Sharon uses 6.3 pints of blue paint and white paint to paint her bedroom walls.
of this amount is blue paint and the rest is white paint.
To find:
The pints of white paint did she use to paint her bedroom walls.
Solution:
We have,
Total paint used = 6.3 pints
Blue paint =
of total paint used
= 
= 
White paint = Total paint used - Blue paint
= 
= 
Therefore, Sharon uses 1.26 pints of white paint to paint her bedroom walls.
Answer:
Area of the resulting rectangle = 23.375 inch²
Step-by-step explanation:
After 1 fold width or length reduces to half.
Area = Length x width
So after 1 fold area will reduce to half.
So we have

Initial area = 8.5 x 11 = 93.5 inch²
Here the paper were folded completely in half, length is reduced to half and width reduced to half, that is
Number of folds = 2

Area after 2 folds = 23.375 inch²
Area of the resulting rectangle = 23.375 inch²
