Answer:
x = -0.76
Step-by-step explanation:
-7x + 29 = 6 (8 + 3x)
-7x + 29 = 48 + 18x
-7x = 48-29 + 18x
-7x = 19 + 18x
-7x-18x = 19
-25x = 19
x = 19/-25
x = -0.76
Answer:
12
Step-by-step explanation:
(whole secant) x (external part) = (whole secant) x (external part)
( 7+x+2) * 7 = ( 6+8) * 6
Combine like terms
(9+x) *7 = 14*6
Distribute
63 +7x = 84
Subtract 63
63 +7x -63 = 84-63
7x =21
Divide by 7
7x/7 = 21/7
x = 3
KM = x+2+7
= 3+2+7
=12
D. f(x)= x*-9x^o+2x^2-4x+10
Answer:
x = 8
Step-by-step explanation:
40 + 6x + 2 = 90 {Complementary angles}
Combine like terms
40+ 2 + 6x = 90
42 +6x = 90 {Subtract 42 form both sides}
6x = 90 - 42
6x = 48 {divide both sides by 6}
6x/6 = 48/6
x = 8
