To answer, we substitute each of the numbers in parentheses to x of h(x) and get the value of g(x).

A. h(2) = 2(2) + 3 = 7 ; g(2) < 4 (neither is equal to 7)

B. h(7) = 2(7) + 3 = 17; g(7) is not shown in the graph (not true)

C. h(2) = 7 ; g(2) < 4 Thus, g(2) < h(2) (choice is not true)

D. From C, g(2) < h(2) (TRUE)

Thus, the answer to this item is letter D.

Factor completely: 4a^2+b^2−c^2+4ab

Lapatulllka [165]

Answer:

$4a^{2} + b^{2} - c^{2} + 4ab$ $= (2a + b -c) (2a + b+c)$

Step-by-step explanation:

Here, the given expression is $4a^{2} + b^{2} - c^{2} + 4ab$

or, the given expression can be written as

$(4a^{2} + b^{2} + 4ab ) - c^{2}$

Now, by ALGEBRAIC IDENTITY: $(x+y)^{2} = x^{2} + y^{2} + 2xy$

So, similarly here, $(2a +b){2} = 4a^{2} + b^{2} + 4ab$

Hence, on simplification, the expression

$(4a^{2} + b^{2} + 4ab ) - c^{2} = (2a + b)^{2} - c^{2}$

Now, by ALGEBRAIC IDENTITY: $(x +y)(x-y) = x^{2} - y^{2}$

So, similarly $(2a + b)^{2} - c^{2}$ $= (2a + b -c) (2a + b+c)$

Hence, the given expression is factorized as:

$4a^{2} + b^{2} - c^{2} + 4ab$ $= (2a + b -c) (2a + b+c)$

4 + [(16 - 4) + (12 -9)] Also Explain the answer please and thank you

dybincka [34]

Answer:

19

Step-by-step explanation:

4 + [(16 - 4) + (12 -9)]

Using PEMDAS, first solve the parentheses.

16-4 is 12 and 12-9 is 3

Rewrite the expression

4+(12+3)

12+3 is 15

4+15

19.
