F(x) = 2x² + 7x - 5
g(x) = -8x² - 3x + 5
g(x) + f(x)
-8x² - 3x + 5 + 2x² + 7x - 5
-8x² + 2x² - 3x + 7x + 5 - 5
-6x² + 4x + 0
-2x(3x - 2)
Hey!
----------------------------------------------
Solution:
Remember to follow PEMDAS!
= 3 + 2 ⋅ [(2 + 1) ⋅ 5 + 8]
= 3 + 2 ⋅ [(3) ⋅ 5 + 8]
= 3 + 2 ⋅ [(15) + 8]
= 3 + 2 ⋅ [23]
= 3 + 46
= 49

Answer:
49

Hope This Helped! Good Luck!
Answer:
x > 8
Step-by-step explanation:
Given
17 < 9 + x ( subtract 9 from both sides )
8 < x , hence
x > 8
We know that
the garden is circular--------------> r=5 ft
Area1=pi*r²=pi*5²=78.50 ft²
path 2 feet by 2 feet square (good soil for the seeds)<span>
Area2=2*2=4 ft</span>²
<span>the probability that a seed will land in the 2 feet by 2 feet square=Area2/Area1
P=4/78.5=0.051 (5.1%)
the answer is 0.051 (5.1%)</span>
