X^2 + 3x - 4 = 6
x^2 + 3x -10 = 0
(x + 5)(x - 2) =0
x = -5 or x = 2
solution set is {-5,2}
Answer:
a) 0.8( 8/10 gives 0.8)
b)0.7( if it was 7/100 it would have been
0.07)
c)3.5( by converting mixed fractions to improper fractions, that is, 3×2+1 and having the same denominator 2… we get 7/2… for the purpose of converting it to decimal, 7×5/2*5= 35/10… by moving one decimal place to the left, we get 3.5)
D) 2.5 ( the same way as c) 5*5/2*5: 25/10 or you can make it to be 5*50/2*50: 250/100 which still gives 2.5)
Answer:
a = 8 (to nearest whole number)
Step-by-step explanation:
Given:
m<B = 36°
m<C = 104°
c = 12
Required:
a
SOLUTION:
✔️First find m<A:
m<A = 180 - (104 + 36)
m<A = 40°
✔️Find a using Sine Rule:
Thus:

Plug in the values

Multiply both sides by sin(40)


(nearest whole number)
2.12=2.120 that is the answer
Answer:
9(w+8) factor 9
Step-by-step explanation:
factor expression
9w+72 divide both side by 9
9/9w+72/9
w+8
