I’m not rlly sure if i did it right & i’m sorry if i didn’t. i used the FOIL method
f= first to first
o=outer to outer
i=inner to inner
l= last to last
so it’d be
8b + 6b = 14b (f)
8b+ 8=16b(o)
-7+6b=-1b(i)
-7+8(l)
and then you add like terms so
[14b+16b-1b]+1
= 29b+1
Answer:
C) -9
Step-by-step explanation:
Exponents in a polynomial must be positive integers. Since your ? has a minus sign in front, its value must be negative. The only such choice is C.
Answer:
9*x*x*x*x*x*x.
Step-by-step explanation:
(3x^3)^2
= 3^2 * x^(3*2)
= 3^2 * x^6
= 9*x*x*x*x*x*x
Answer:
A = 63.585 mm or round if needed
Step-by-step explanation:
Formula is A = pi radius squared
9 mm ÷ 2 mm = 4.5 mm
3.14 x 4.5 x 4.5= 63.585 mm
Hope this helped have a great day :)
It might be at least 63.585 I don't have all the info
Answer:
13
Step-by-step explanation:
<em>c</em> is the hypotenuse. c = √a^2+b^2. To clarify, both a squared and b squared should be under the square root symbol.
