Can you Solve. 3x^2+10x+3

2 answers:

6 0

You cannot solve for x but you can factor

to solve in ax^2+bx+c form you must find
b=x+y
a times c=x times y

so solve

3 times 3=9

what 2 number multily to get 9 and add to get 10
9=x times y
the numbers are 9 and 1 so

3x^2+1x+9x+3
(3x^2+1x)+(9x+3)
factor
(x)(3x+1)+(3)(3x+1)
reverse distribute
ab+ac=a(b+c)

(x)(3x+1)+(3)(3x+1)=(x+3)(3x+1)
factored out form is (x+3)(3x+1)

Simplifying
3x^2 + 10x + 3
Reorder the terms
3 + 10x + 3x^2
Factor a trinomial
(3 + x)(1 + 3x)
Final result
(3 + x)(1 + 3x)

How do you do this? please help me

Answer:

f = 10, g = 4.8 cm

Step-by-step explanation:

Area of ABCE = 60 cm²

Area of ABCD = 48 cm²

So,

Area of ADE = 60-48

=> 12 cm²

Area of ADE = $\frac{1}{2} (Base)(Height)$

Where Area = 12 cm², Base = 4 cm

12 = $\frac{1}{2}(4)(Height)$

Height = 12-2

Height = 10 cm

Where Height is AD

So, AD = 10 cm

Also, AD is parallel and equal to BC $(f)$

So,

f = 10 cm

Now, Finding g

Area of ABCD = $Base * Height$

Where Area = 48 cm², Base = 10 cm

48 = 10 * Height

Height = 48/10

Height = 4.8 cm

Whereas, Height is g

So, g = 4.8 cm
