Answer:
Often, the simplest way to solve "ax2 + bx + c = 0" for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it doesn't factor at all, or you just don't feel like factoring. While factoring may not always be successful, the Quadratic Formula can always find the solution.
The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.
Given that these triangle are right triangles, we use the Pythagorean theorem to calculate the missing lengths which is c and it is the hypotenuse. We calculate as follows:
<span>a = 7.5 cm, b = 10.6 cm
c</span>² = a² + b²
c² = 7.5² + 10.6²
c = 12.98<span>
a = 13 cm, b = 7.5 cm
</span>c² = a² + b²
c² = 13² + 7.5²
c = 15.00<span>
a = 7.5 cm, b = 13 cm
</span>c² = a² + b²
c² = 7.5² + 13²
c = 15.00<span>
a = 5 cm, b = 13 cm
</span>c² = a² + b²
c² = 5² + 13²
c = 14

Answer:
<h2>
3p+6
</h2>
Step-by-step explanation:
8p+7−(5p+1)
=8p+7+−1(5p+1)
=8p+7+−1(5p)+(−1)(1)
=8p+7+−5p+−1
=8p+7+−5p+−1
=(8p+−5p)+(7+−1)
=3p+6
and thats how you get the answer
