<h3>Answer: B+E = 180</h3>

Angles B and D are corresponding angles. This means D = B since corresponding angles are congruent when we have parallel lines.

Then note how D+E = 180 as these two angles form a straight angle.

Replace D with B getting B+E = 180 (this is the substitution property).

Alternatively, you can say that G = E and B+G = 180 to lead to B+E = 180. There are many other routes to take as well.

Can some answer this math question

-BARSIC- [3]

Answer:

Step-by-step explanation:

To multiply powers of a variable, add the exponents:

$x^m\cdot x^n = x^{m+n}$

This rule works for all exponents, positive, negative, or zero. Also, remember that $x^0=1$ .

Also, remember the definition of negative exponent: $x^{-n} = \frac{1}{x^n}$

To multiply the two monomials, start by multiplying the coefficients, 14 and 4. That gives 56, so your answer begins with 56.

Now for the powers of x, $(x^3)(x^{-5}) = x^{3+(-5)} =x^{-2} = \frac{1}{x^2}$

For the powers of y, $(y^{-4})(y^4)=y^{4+(-4)} = y^0 = 1$ $(y^{-4})(y^4) = y^{-4+4} = y^0 =1$

Your answer is

$56 \cdot \frac{1}{x^2} \cdot 1 =\frac{56}{x^2}$
