5x^2 + 42x + 16 what would the area be if x = 5

Mathematics
1 answer:
Anna11 [10]3 years ago
3 0

Answer:

The area would be 301 if x=5.

Step-by-step explanation:

Given expression is:

5x²+42x+16

We have to find the area when x=5

So putting x=5 in the given expression.

Area = 5(5)²+42(5)+16

Taking square of 5 and multiplying 42 by 5

Area = 5(25)+210+16

Area = 75+210+16

Adding all the terms

Area = 301

Hence,

The area would be 301 if x=5.

Help i need the answer by 10am December 23
Sever21 [200]

Answer:

Simon:         55     hours

Alvin:           70     hours

Theodore:  <u>159</u>   hours

Total:         284  hours

Step-by-step explanation:

Let A, T, and S stand for the hours worked by Alvin, Simon, and Theodore.

We are told that:

A = S + 15,

T = 3S - 6

and

A + S + T = 284

Note that the first two equations state the value of A and T in terms of S.  Let's use them in the third equation, so that we'll have only one unknow:

A + S + T = 284

(S + 15) + S + (3S - 6) = 284

5S + 9 = 284

<em><u>S = 55</u></em>

Now use this value of S in the first two equations to find A and T:

A = S + 15

A = 55 + 15

<u><em>A = 70</em></u>

T = 3S - 6

T = 3*55 - 6

<em><u>T = 159</u></em>

<u></u>

<u>(55 + 70 + 159) = 284</u>

<u></u>

Suppose that a researcher wanted to measure the federal government's efforts to make the education of its citizens a priority. T
Vitek1552 [10]

Answer:

Step-by-step explanation:

STRENGTHS

1) Budget is a major pointer to a government's commitment in a particular sector. Money allocated for education versus the %GDP will definitely show if education is a priority for the government or not.

WEAKNESSES

1) The major player, (the citizens) is not the determinant in this measure.

2) Without knowing the actual number or estimate of those who would be captured in this budget it may be impossible to know if education was really the priority of the government. Let's say (X) number of persons will benefit from the education budget, if X is unknown then planning would be on assumptions.

3) Budget alone is not sufficient in determining the commitment of the government in a sector. Laws, policies as well play a huge role and in this research laws,and policies are not part of the determining indices.

Ep-8 if grounded aboard a small powerboat, which is a method to help free yourself?
andreyandreev [35.5K]
<span>Grounding on boats is something like a mystery to most of the people. They think that the factory hooked it up like that and therefore the installation must be correct. But that's something which will not work every time.</span>
Thus if you are grounded aboard a small powerboat then place everybody aboard in the center of the boat and<span> t</span>ry to kedge your boat off the obstruction.
