sub 2 for any "x"
3(2)^2-2(2)+1
6^2-4+1 i dont know if you need to simplify even more but if you do
36-4+1 32+1 31
i hope this helps you!
Answer:
The answer is 9.
Step-by-step explanation:
Hey there, so it looks to me that you just have to subsitute 2 in for x, and solve the equation. Like this.
1. Plug in X: 3(2)^2 -2(2) + 1
2. Solve exponents (2)^2 = 4, so the equation is 3(4) - 2(2) + 1
3. Multiplication: 3 × 4 = 12, and -2 × 2 = -4, so the equation is 12 - 4 + 1
4. Addition: -4 + 1 = -3, so it is now 12-3
5. Subtraction: 12-3 = 9, so the answer is 9!
I hope this helps.

y=60° opposite angles of a parallelogram are congruent.
? = 180-52-60 co- interior

Need help please I'm not sure if I'm right
Answers
Answer:
58
Step-by-step explanation:
The angles inside a triangle always sum to 180°. We already have a 32° angle and a 90° - totalling 122° - and when we add x°, we'd like the sum to be 180°. So x must be 180 - 122 = 58.
Answer:
58
Step-by-step explanation:
The total should be 180 degrees. We know the the top angle is 32 degrees and the bottom left is 90 degrees because it has a square there. So 32+90=122. If we subtract 122 from 180 we are left with 58 degrees so x=58
Multiplying by which number is equivalent to an increase 49.5%
Answers
Answer:
22.46
Step-by-step explanation:
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
49.5% = 49.5/100 = 49.5 ÷ 100 = 0.495.
100% = 100/100 = 100 ÷ 100 = 1.
Increase the number by 49.5% of its value.
Percentage increase = 49.5% × 22.46
New value = 22.46 + Percentage increase

Henry has 96 marbles. He is packing containers with 8 marbles in each container. How many containers, c, does Henry need to pack all the marbles?
96 − c = 8
96 = 8 x c
c = 96 + 8
8 ÷ c = 96
Answers
so 96= 8xC
because we know there’s 96 total, and only 8 per c , this would be the setup
Estimation on a scale drawing of a fence, 3.75 inches represent 24 feet . what. is the actual length of a second fence is 2.8 inches in the drawing?
The exact length of the second fence is __ feet.
Answers
Answer: 17.92 feet
Step-by-step explanation:
From the question, we are informed that the estimation on a scale drawing of a fence is that 3.75 inches = 24 feet.
Based on the above, 1 inch will be:
= 24/3.75
= 6.4 feet
Therefore, the actual length of a second fence that is 2.8 inches in the drawing will be:
= 6.4 × 2.8
= 17.92 feet
9. Use the graph of each polynomial function to find the factored form of the related polynomial.
Assume the polynomial has no constant factor.
A.
What are the zeros of this function? (2 points)
what is the factorization of the polynomial
Answers
Answer:
A) the zeros are; x = -2 and x = 4
B) y = (x + 2)(x - 4)
Step-by-step explanation:
A) The zeros are the values of x where the graph curve crosses the x-axis.
Looking at the graph, the curve crosses the x-axis at x = -2 and x = 4
Thus, the zeros are; x = -2 and x = 4
B) Factorization of the polynomial means that we transform the zeros into the polynomial.
Thus, we have; y = (x + 2)(x - 4)
So when y is zero, x = - 2 or 4 as earlier derived.

the dress?
Answers
Answer:
$50
Step-by-step explanation:
Given data
We are given that the price is $40
the markup percent is 25%
Hence the price will be
40+25% of 40
=40+ 25/100*40
=40+ 0.25*40
=40+10
=$50
Therefore, the price of the dress is $50

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

I want to help you on the first thing you said,
so always consider a percent as a fraction but there denominator is ALWAYS 100 (a way to remember that is that the word "cent" means 100). The word "of" means multiplication so that means your multiplying it with 50 and just do the multiplication.
