Evaluate the following expression when x=14. X^2+5x+11
Answer:
277
Step-by-step explanation:
14^2+5(14)+11=
196+70+11=
277
Start by substituting 14 in for x everywhere that x appears in the problem.
So we have (14)² + 5(14) + 11.
Remember that PEMDAS tells you to deal
with your exponents before multiplying.
So you must square the 14 to get 196.
So we have 196 + 5(14) + 11.
Now multiply 5(14) to get 70.
So we have 196 + 70 + 11.
Now we can simply add to get 277.

x2y4(x2 - 16) - 9y4(x4 - 16) how do i simply this?
Answer:
The simplified expression is given as
[tex]8x^2y^4(17x^2-2)[/tex]
Step-by-step explanation:
step one:
Given the expression
[tex]x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)[/tex]
step two:
First, let us open the bracket we have
[tex]x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)\\\\x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\[/tex]
step three:
collect like terms we have
[tex]x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\x^4y^4-9x^4y^4+144x^4y^4-16x^2y^4\\\\-8x^4y^4+144x^4y^4-16x^2y^4\\\\136x^4y^4-16x^2y^4\\\\\\[/tex]
step four:
we can now factor out [tex]8x^2y^4[/tex]we have
[tex]8x^2y^4(17x^2-2)[/tex]
The sum of 3 consecutive integers equals -3. What are the 3 integers?
Answer: 0, -1, -2

Find x and y. Give reasons to justify your solution.
Answer:
x = 36
y = 22
Step-by-step explanation:
Let's solve for x
<EOG is a right angle due to the marking. Since that's the case, m<EOG = 90.
<EOF + <FOG = <EOG
Now let's substitute the values in.
54 + x = 90
x = 36
Let's solve for y
<AOB is 180 because it's a line.
<BOD + <COB = 180 because of supplementary angles
<BOD + 156 = 180
<BOD = 24
Let's create the equation now.
<AOE + <EOF + <FOG + <GOD + <BOD = <AOB
Now let's substitute the values in.
y + 54 + x + 2y + 24 = 180
3y + x + 78 = 180
Now let's substitute 36 for x.
4y + 36 + 78 = 180
3y + 114 = 180
3y = 66
y = 22

You read 9.75 pages in your science book and 24.5 pages of a play for English class. It takes you 1.2 minutes to read each page of science and 0.8 of a minute to read each page of the play. How much time do you spend reading?
CLEAR CHECK
Answer:
31.3 minutes were spent reading
Step-by-step explanation:
If it takes 1.2 minutes to read each page for science and you read 9.75 pages of science, then you must multiply these two numbers together
9.75 pages × 1.2 mins = 11.7
If it takes 0.8 of a minute to read each page of the play and you read 24.5 pages of a play, then you also multiplying these two numbers
24.5 pages × 0.8 mins = 19.6
If we must find out the time spent reading, we must add these two numbers together
11.7 + 19.6 = 31.3

What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
Takira is an arrangement setter for a deals association. She makes $12 an hour in addition to a $3 charge for every arrangement that is planned.
Let 'x' be the number of hours and 'y' be the number of appointments. Then the equation is given as,
Total earnings = $12x + $3y
This week. Takira worked 40 hours and scheduled 31 appointments. Then the total earnings are calculated as,
Total earnings = $12(40) + $3(31)
Total earnings = $480 + $91
Total earnings = $571
The total earnings with fees this week will be $571.

2h = W-3p
(solve for p)
Answer:
p = (2h-W)/-3
Step-by-step explanation:
2h - W = -3p
divide both sides by -3
(2h-W)/-3 = p
The value of p is w/3 - 2h/3.
What is equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S
Given:
2h = W-3p
For p move w
2h - w = -3p
Now, divide both side by 3
2h/3 - w/3 = -3p/3
2h/3 - w/3 = -p
p= w/3 - 2h/3
Hence, the value of p is w/3 - 2h/3.

$35
withdrawal -$70
withdrawal -$50
Answer:
5
Step-by-step explanation:
The account balance after transactions will be $90.
What is Addition?
A process of combining two or more numbers is called addition.
Given that;
The account started with a balance of $125 and
deposit $50,
deposit $35
withdrawal -$70
withdrawal -$50
Now,
Deposit in account means to add the amount and withdrawal means to remove money from account.
Since, The account started with a balance of $125.
After deposit $50,
The account balance = $125 + $50 = $175
Again after deposit $35;
The account balance = $175 + $35 = $210
After withdrawal -$70;
The account balance = $210 - $70 = $140
Again after withdrawal -$50;
The account balance = $140 - $50 = $90
Thus, The account balance after transactions will be $90.
