I think it’s C cuz I took this too
Answer:
12 x^5y^12
Step-by-step explanation:
3x^2y^5 * 4x^3y^7
Multiply the constants
3*4 = 12
Multiply the x terms
x^2 * x^3
We know a^b* a^c = a^(b+c)
x^(2+3) = x^5
Multiply the y terms
y^6 * y^7 = y&(5+7) = y^12
Put them back together
12 x^5y^12

Answer:
B) 40
Step-by-step explanation:
Vertical angle XZU has the same measure as the given angle, 130°. It is equal to the sum of right angle XZV and unknown angle UZV. So, ...
∠UZV +90° = 130°
∠UZV = 40° . . . . . . . . . subtract 90°
Answer:
a) 888,888
b) 200,00
c) 888,888-200,000=688,888
step-by-step explanation:
the biggest number possible is 888,888 because 8 is the largest number and the question doesn't say that you have to use each number
200,000 is the smallest number because outside 0, 2 is the second-smallest number, and since 000,000 isn't a number 200,000 is the next best thing
good luck :)
i hope this helps
brainliest would be highly appreciated
have a nice day!

there's a quick graph below of the bounds and the tangent at "c"
not happening -2 or 2 will have a tangent parallel to a,b, needless to say -2 is out of the range [a,b] anyway, so the only value is really 1, on the positive 1st quadrant
