Answer:

( 3x + 1) (2x+5)

Step-by-step explanation:

6 x ^2 + 17 X + 5​

We break the 6 into 3 and 2

(3x    ) (2x   )

We need the middle term to be 17

( 3x + 1) (2x+5)

3*5+2 = 17 so it works

2 more geometry questions for 15 points and a brainliest if correct
Marrrta [24]

Answer:

1. x = 5

Step-by-step explanation:

1.

The Trapezoid Midsegment Theorem states that a line segment connecting the midpoints of the legs of the trapezoid is parallel to the bases, and equal to half their sum.

In this problem you can see that 5x - 1 is the midsegment of the trapezoid, so using the rule:

(21 + 27) / 2 = 5x -1

solve:

48/2 = 5x-1\\24 = 5x - 1\\25 = 5x\\x= 5

2. Diagonals are congruent

You can see in this picture that the diagonals are not always congruent:

What is the value of eight to the power of 0
Lera25 [3.4K]

Answer:

1

Step-by-step explanation:

So when we raise a number to the zeroth power, that means we multiply the number by itself zero times - but that means we're not multiplying anything at all! ... In short, 0 is the only number such that for any number x, x + 0 = x.

hope this helps
