Answer
-3.75
Step-by-step explanation:
17=-13-8x (collect like terms )
17+13=-8x
30=-8x (divide both sides by -8)
30/-8=-8x/-8
-3.75=x
<span>The answer is The total area of the top and bottom squares. s = √7 cm is irrational value and we need rational value. Let's check all choices: A. The volume. V = (s)^3. If s = √7, V = (√7)^3 = 7√7 - irrational value. B. The perimeter of the front square. P = 4 * s = 4 * √7 = 4√7 - irrational value. C. The diagonal of the back square. d = s√2 = √7 * √2 = √(7*2) = √14 - irrational value. D. The total area of the top and bottom squares. A = 2 * s^2 = 2 * (√7)^2 = 2 * 7 = 14 - rational value.</span>
Answer:
,
Step-by-step explanation:
we know that
In a parallelogram, opposite angles are congruent and consecutive angles are supplementary
so
----> equation A
-----> equation B
we have

substitute in the equation B and solve for m<R


-----> substitute in equation A
