What is the degree of 6x5 - 4x2 + 2x3 - 3 + x?

55555555555555555555

Step-by-step explanation:

(I am assuming that for example, in 6x5 the exponent is 5, so the expression is 6x⁵ - 4x² + 2x³ - 3 + x)
Finding the degree of a polynomial is really simple. All you have to do is find the largest exponent in the polynomial, so in this case, the degree is 5 (Yes, my previous answer is wrong) and not 26. I don't know how you got 26. 
Another example: In 3x² - 8x⁷ + 6xy⁴, the degree is 7. 

See below

Step-by-step explanation:

Part A

As per diagram the triangles CGB and PEB are similar

Part B

ΔCGB and ΔPEB similar because:

CG║PE sides of parallelogram∠CBG ≅ ∠PBE as vertical angles∠CGB ≅ ∠PEB  and ∠GCB ≅ ∠PEB as CG║PEPart CBE =?PE=?

Corresponding sides of similar triangles are in same proportion, so;

BP/CB = PE/CG= BE/GB250/350 = PE/400 = BE/450

Therefore

BE = 250*450/350= 321.42 ftPE = 400*250/350 = 285.71 ft
