Answer:

$2.23 \times 10^{5}$

Step-by-step explanation:

We have to find the sum of two numbers following the steps as described in the question.

The question is in the form of fill in the blanks.

Now, the given sum is $(3.3 \times 10^{4} )+(1.9 \times 10^{5} )$

= $(3.3 \times 10^{4} )+(19 \times 10^{4} )$

= $(3.3+19) \times 10^{4}$

= $22.3 \times 10^{4}$

= $2.23 \times 10^{5}$ (Answer)

Please help me, I have no clue what its asking and I have to explain it in class tomorrow morning

Nat2105 [25]

Answer:

The term was obtained by grouping and adding the all x terms in the expression.

Step-by-step explanation:

The example has already provided this step:

(x -4) +(x +1) +(¼x +5)= $\frac{9}{4} x + 2$

Thus, the question is asking how is $\frac{9}{4} x$ derived from the expression.

The attached picture shows the intermediate working to arrive at the final perimeter expression.

This expression is later equated to 20 since it is given that the perimeter of the traingle is 20 inches.

Given g(x)= 4x+4, find g(4)

Kipish [7]

$\large\underline{\bf\red{Solution:-}}$

Given that : g(x) = 4x + 4 .

So , in order to find the value of g(4) , just substitute x = 4 in the given function .

Here ,

=> g(x) = 4x + 4 .

=> g(4) = 4 × 4 + 4 .

=> g(4) = 16 + 4 .

=> g(4) = 20 .

Hence the required answer is 20.
