Find the value of polynomial 2x - 3x2 + 4x -7 at x = 2.​

13

Step-by-step explanation:

Given the polynomial :

3x² + 4x -7 at x = 2.​

Substitute x = 2 into the equation :

3(2)² + 4(2) -7

3(4) + 8 - 7

12 + 8 - 7

= 13

Hence, vlaue of the polynomial at x = 2 is 13

16

step-by-step explanation:

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
