Answer: 7(x+2)(x+3)
Step-by-step explanation:
First, you want to find the GCF, 7 goes into all the terms evenly
so 7x^2 + 35x + 42 = 7(x^2 + 5 + 6)
to factor (x^2+5+6), you want to find two numbers whose product is 6 and whose sum is 5 (2 and 3)
so (x^2 + 5 + 6) becomes (x+2)(x+3)
and 7(x^2 + 5 + 6) becomes 7(x+2)(x+3)
I think your suppose to combine like terms to find your answer.... Like for example 5x+2=6x+11
what I did first was combine my x's which is 5x+6x is 11x
then I added 2+11 and that gave me 13 so I put it together and got 11x+13
The slide and the ladder made a right angle triangle with the ground. The angle that the slide made with the ground is labeled as
in the diagram below. We can use the trigonometry ratio to work out the size of the angle.
8.3 is the side opposite to the angle and 14.5 is the hypotenuse. We need to use the Sin ratio

<span>A) X + y + z = 7
B) 2x − y + z = 7
C) 3x − z = 2
</span><span>C) z = 3x -2 Substituting this into equations A) and B)
</span>
<span>A) X + y + 3x -2 = 7
B) 2x − y + 3x -2 = 7 Adding A and B
3x + 6x -4 = 14
9x = 18
x = 2
</span>Since x = 2 then
<span>A) 2 + y + 6 -2 = 7
</span><span>A) y = 1
</span>A) X + y + z = 7
<span>A) 2 + 1 + z = 7</span>
z = 4
