Let, the number of toy trucks = x
Then, number of toy cars = (x + 12)

Now, we have: x + x+12 = 38
2x + 12 = 38
2x = 38 - 12
2x = 26
x = 26/2
x = 13

So, there are 13 toy trucks in total.

Hope this helps!

2x^{2} +4x+1=0 <br> Solve for x.
Viefleur [7K]
2x^2 + 4x + 1 = 0

2x^2 + 4x + 1 - 1 = 0 - 1

2x^2 + 4x = -1

X(2x + 4) = -1

X = -1.

2x + 4 = -1
2x + 4 - 4 = -1 - 4
2x = -5
2x/2 = -5/2
X = -5/2.

I believe these are the solutions. If not you can use the quadratic formula to solve for the roots, solutions.

What is the product of 2x + y and 5x – y + 3?
hoa [83]

Answer:  The required product is 10x^2-y^2+3xy+6x+3y.

Step-by-step explanation:  We are to find the product f the following two algebraic expressions:

E_1=2x+y,\\\\E_2=5x-y+3.

To find the product of the above two expressions, we must multiply each term of the first expression with each term of the second expression.

The multiplication is as follows:

M\\\\=E_1 \times E_2\\\\=(2x+y)\times(5x-y+3)\\\\=10x^2-2xy+6x+5xy-y^2+3y\\\\=10x^2-y^2+3xy+6x+3y.

Thus, the required product is 10x^2-y^2+3xy+6x+3y.

23 POINTS HERE PEOPLE
SOVA2 [1]

Hello!  

<h2>Answer: </h2>

23. 138 people voted for Nyemi, 69 people voted for Luke, and 23 people voted for Natalie.

24. Reina did not ride 11/16 of the rides.

<h2>Explanation:</h2>

23:

3 ÷ 5 = 0.6

230 × 0.6 = 138

230 × 0.3 = 69

230 × 0.1 = 23

24:

We know that Alberto rode 5/8 of the rides at the park, and Reina rode half of this.

5/8 × 1/2 = 5/16

16 - 5 = 11

Due: Today @11:59 <br> (Need) Explanation 3-5 sentences of how you got the answer
kifflom [539]

You can use the pythagorean theorem.

a^2+b^2=c^2

a=9

b=b

c=41

9^2+b^2=41^2

81+b^2=1681

b^2=1600

b=+/-40

but since this is a geometric scenario, answers will only lie in the positive real number set. That's why answer is +40 or C.
