Answer: x=1/2 or x=2

2x^2 - 3x = 2x - 2
2x^2 -5x + 2


Factoring:
1. find the two numbers that multiply to equal ac (2 • 2) and add to equal b (-5)
The numbers = -4, -1

2. Extend the b term into these two numbers.
2x^2 -4x - x + 2

3. Group the first two terms and the last two terms to each other.
(2x^2 - 4x)(-x + 2)

4. Take out the GCF's in the parentheses sections. Note: the terms inside both of the parentheses should be equal, or you have done something wrong.
2x(x - 2) - 1(x - 2)

5. Group the GCF's together alongside the equivalent parentheses sections.
(2x - 1)(x - 2)


You're done here, but IF you want to find the solutions, you have to set each of the new parentheses sections to zero and solve for x.
2x - 1 = 0 >> 2x = 1 >> x = 1/2
x - 2= 0 >> x = 2


In conclusion, your solutions are x = 1/2 and x = 2, and your factored equation is (2x - 1)(x - 2)


Hope this helps!!

PLZZZ problem 25 HELP
Arturiano [62]

Answer: 72 cm²

Step-by-step explanation: 1/2(base)(height) is the formula to find the area of a triangle. To find the area of the bigger triangle we substitute 10 cm for the base and 6 cm for the height.

1/2(10)(6)

1/2(60)

30 cm²

since we have two of the same triangles, we double that

we also have a smaller triangle. 14-10=4 which is the base of the smaller triangle.

1/2(4)(6)

1/2(24)

12 cm²

now, we add everything

60 cm² + 12 cm² = 72 cm²

Someone please help me w this standard form question​
svp [43]

Answer:

2.4 × 10⁶

Step-by-step explanation:

Given:

  • \sf x=3.8 \times 10^5
  • \sf y=5.9 \times 10^4

To calculate the value of R, substitute the given values into the given formula:

\begin{aligned}\sf R & = \sf \dfrac{x^2}{y}\\\\ \implies \sf R& = \sf \dfrac{(3.8 \times 10^5)^2}{5.9 \times 10^4}\\\\& = \sf \dfrac{3.8^2 \times (10^5)^2}{5.9 \times 10^4}\\\\& = \sf \dfrac{14.44 \times 10^{10}}{5.9 \times 10^4}\\\\& = \sf \dfrac{14.44}{5.9} \times \dfrac{10^{10}}{10^4}\\\\& = \sf 2.4474... \times 10^{(10-4)}\\\\& = \sf 2.4474... \times 10^6\\\\\end{aligned}

Therefore, the value of R to 1 decimal place is 2.4 × 10⁶
