2y = 4x - 12 \\ y =  - 2x + 2 \\  \\ 2( - 2x + 2) = 4x - 12 \\  - 4x + 4 = 4x - 12 \\ 4 = 8x - 12 \\ 16 = 8x \\ 2 = x \\  \\ y =  - 2(2) + 2 \\ y =  - 4 + 2 \\ y =  - 2

I need help on this question, It's for Algebra 1 Simplify the following expression. (7x2 + 4x - 7) + (4x2 - 6x + 4)
Drupady [299]
You can only add like terms

exg
you can addd
2+4
2x+4x
2x^2+4x^2
2x^3+4x^3

but not
2+4x
2x^2+2x^3


so when adding like terms keep the exponent
4x+2x=6x
4x^3+2x^3=6x^3

(7x^2+4x-7)+(4x^2-6x+4)
get rid of the parenthasees
7x^2+4x-7+4x^2-6x+4
group like terms (x^2 with x^2 x with x, etc)

(7x^2+4x^2)+(4x-6x)+(-7+4)
add like terms
11x^2-2x-3

What is the lcm of 56 and 136
Citrus2011 [14]

Answer:

LCM(56,136)=952

Step-by-step explanation:

To find the LCM of two numbers, factorize both these numbers:

56=2\cdot 28=2\cdot 2\cdot 14=2\cdot 2\cdot 2\cdot 7=2^3\cdot 7\\ \\136=2\cdot 68=2\cdot 2\cdot 34=2\cdot 2\cdot 2\cdot 17=2^3\cdot 17

These two numbers have the common factor of 2^3.

Now multiply this common factor by the remaining factors:

LCM(56,136)=2^3 \cdot 7\cdot 17=952

Therefore, the LCM is 952.

Please help!! Xoxo! Appreciate it :)
Degger [83]

Answer:

B   x = sqrt(41)

Step-by-step explanation:

Since the large triangle is isosceles, the smaller triangles on the right side and left side are congruent right triangles.

The base of each smaller right triangle is 4 units long (8/2 = 4).

The vertical leg is 5.

Use the Pythagorean theorem to find x.

a^2 + b^2 = c^2

4^2 + 5^2 = x^2

16 + 25 = x^2

x^2 = 41

x = sqrt(41)

Answer: B   x = sqrt(41)
