Answer: 16x + 16
(2x+4)² is the large square ; (2x)² is the small square
the area of the colored figure in a letter phenomenon is
(2x + 4)² - (2x)² = 4x² + 16x + 16 - 4x² = 16x + 16

Answer:
Tom weighs 70 pounds
Step-by-step explanation:
first, you have to set up your equation which would be, x + 3x = 280.
The x stands for Tom's weight and the 3x stands for three times Tom's weight for the dad. You would then add your like terms, then divide by 4 to get 70.
x + 3x = 280
4x = 280
280/4 = 70
x = 70
Hope this helps!
Answer:
14
Step-by-step explanation:
Follow DMAS formula:
DMAS rule is followed when multiple arithmetic operations are there in a given problem like addition, subtraction, multiplication and division. It tells they should be performed in order of Division, Multiplication, Addition and Subtraction.
=50+6*3 -82
=50+18-82
=68-82
=14
Answer:
Combination
Step-by-step explanation:
Here by 10C7 we actually mean, 
And the formula for evaluating mCn is
Therefore
10C7 =
Where m! is called m factorial and can be evaluated as
m!= m*(m-1)*(m-2)*(m-3)*.......3*2*1
Hence
10!= 10*9*8......*3*2*1
7!= 7*8*6.....3*2*1
3!=3*2*1
With these we can evaluate
10C7
Hence the answer is D
Answer: A
Step-by-step explanation:
The polynomial has roots at 
.
So, the equation should have factors of 
.
This eliminates everything except for A.
