Answer:
(x-8) (x+7)
Step-by-step explanation:
x^2 -x-56
We want to factor this problem.
What two numbers multiply to negative 56 and add to -1
-8 *7 = -56
-8+7 = -1
We can use -8 and 7
(x-8) (x+7)
Check:
FOIL
first: x*x =x^2
outer: 7x
inner:-8x
last: -8*7 = -56
Add this together
x^2 +7x-8x -56 = x^2 -x-56
Let the balance = Y and the number of weeks = x
She takes out 15 per week, so multiply 15 by x ( the number of weeks) to get 15x.
You would then want to subtract that from the amount she started with in her account.
The equation becomes: Y = 150 - 15x
Answer:
D. sin J = Cos L
Step-by-step explanation:
LK = √219² - 178² = 127.58
sin J = <u>LK/LJ</u> =127.58/219 = 0.58
Cos L = <u>Lk/LJ</u> = 0.58
sin L = 178/219 = 0.81
Cos J = 178/219 = 0.81
Tan J = 127.58/178 = 0.72
tan L = 178/127.58 = 1.40
Answer:
38.9
Step-by-step explanation:
Sin x = opposite/hypotnuse
Sin-1 = 32/51
=38.86
=38.9
