Answer:
Annie's height= 49 cm
Her brother's height= b+ 49
Let the sum be represented as x
x- 49 = b
Answer: the length and width are
(x + 8) and (x + 8)
Step-by-step explanation:
The rug has an area represented by the expression
Area = 4x² + 64x + 256.
The factors in the factored expressions represent the length and width of the rug.
Dividing the the equation by 4, it becomes
x² + 16x + 64 = 0
We would find two numbers such that their sum or difference is 16x and their product is 64x^2.
The two numbers are 8x and 8x. Therefore,
x² + 8x + 8x + 64 = 0
x(x + 8) + 8(x + 8) = 0
The factors are
(x + 8)(x + 8)
Answer:
turn the decimal into a whole number by multiplying by 10, 100 (what you do to one number you must do to the other)
multiply both by 10 it then becomes
540/75 = 7.2
it's easier to divide whole numbers and is the same answer as 54/7.5
Answer:
Those answers are correct that are shown and that are shown in blue
Step-by-step explanation:
Answer:
The correct equation is 8.7 + b = 54.6
Step-by-step explanation:
because it is given that measure of side a is 8.7cm, in all other equations the values of a is different.
