Hello,
The correct answer is B) 280 in²
= 10( 2 × 9 + 10 )
= 10 (2 × 9 = 18 + 10 = 28)
= 10 × 28 = 280
= 280
Answer: 280 in²
In other words.....
= 10(2*9+10)
= 10(18+10)
= 10*28
= 280
Answer: 280 in²
Hope this helps!!!! (:
Answer:
hello : k = - 9
Step-by-step explanation:
h(x) =x²+3 and g(x) = x² - 6.....(*)
g(x) = x² +3 + k.....(**)
by (*) and (**) : 3+k = -6
3+k - 3 = - 6 - 3
k = - 9
Answer:
Step-by-step explanation:
take angle A as reference angle
using cos rule
cos A=adjacent/hypotenuse
cos A=12/13
cos A=0.92
A=cos 23
A=23 degree
for ratio,
cos A=12/13
B. Step 1. 14x - 6 = 9
Step 2. 14x = 15
You multiply it together like (a+b)(a+b)
the answer would be a^2 + 2ab + b^2
