Answer:
<u>60+150</u> (210)
Step-by-step explanation:
The Distributive property says a(b+c)=ab+ac
<u>6(10+25)</u>
1) Distribute the 6 to 10:
60
2) Distribute the 6 to 25:
150
3) Add the two terms together:
210
Hello,
g(x)=x²+3
f(x)=2/x
so f(g(x))=f(x²+3)=2/(x²+3)
Explainations:
f(y)=2/y
f(4y)=2/(4y)
f(x²)=2/x²
f(x²+3)=2/(x²+3)
Answer:
B
2(6)+4 > 16 x > 6 2(7) + 4 > 16
12+4=16 14+4>16 18>16
Dot product is
a*b = |a|*|b|*cosα.
In our case
u*u =|u|*|u|*cos 0
u*u =|u|*|u|
12=|u|²
|u|=√12=√(4*3)=2√3

Answer:
10
Step-by-step explanation:
height = 2(Base) + 4
h = 2b + 4
Area of Triangle
A= bh/2
15 = b (2b) +4) / 2 multiply both sides by 2 and distribute the b
30 = 2
+ 4b Divide everything by 2
15 = + 2b Subtract 15 from both sides
+ 2b -15 = 0 Look a quadratic. Factor or use quadratic formula
b = 3 or b = -5 Measurements of length can't be negative. So its 3
h = 2(3) + 4 Substitute 3 in to find height
h = 10
