Given the equation 1/2(d + 4) = 4.25, what is the value of d? 2
d = 4.5
d = 3.75
d = 0.25
d = 8

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

-1   1/6.   you dont subtract the denominators
