we are given
DEF is a line
so, sum of angles must be 180
angle(DEG)+angle(GEF)=180
now, we can plug values
.........Answer
vertically opposite angle must be equal
angle(GEF)=angle(DEH)
now, we can plug values
now, we can plug x=16
...................Answer
7-(8*7)+(8*6)+(8*5)+(8*4)+(8*3)+(8*2)+(8*1)=7-56+48+40+32+24+16+8= 217*217= 47089
Answer:
x² - 25
Step-by-step explanation:
Given:
(x-5)(x+5)
Find:
Product
Computation:
(x-5)(x+5)
(a+b)(a-b) = a² - b²
(x-5)(x+5) = x² - 5²
(x-5)(x+5) = x² - 25
Alternate:
(x-5)(x+5)
x² + 5x - 5x - 25
x² - 25
Answer:
It would be {10, 16, 27}, {12, 27, 39}, {8, 22, 31} that DO NOT represent 3 sides of a triangle
Step-by-step explanation:
Since the only answer where the first 2 numbers is greater than the 3rd/last number is {14, 28, 39} (which makes it the only traingle), the others would ALL NOT be triangles.
T remains the same, as for the other two, just add 8 to their y values and keep the x values the same.
