Answer:
the answers are -243 and 729
Step-by-step explanation:
you multiply each by -3. 1x-3 gives you -3. -3x-3 gives you 9. -3x9 gives you -27. -27x-3 gives you 81. 81x-3 gives you -243 and -243x-3 gives you 729. i hope this helps.
4x^2+23x-72=
4x(x+8)-9(x+8)=
i got dis 4 yo answer and it is (x+8)(4x-9)
hope dis helped
Answer:
A = 90, B =18
Step-by-step explanation:
From the question
The weight of meteorite A is five times the weight of meteorite B, ill get this equation
A = 5B
if their sums of their weights is 108 tons, find the weight of each, ill get this equation
A+B = 108
Now since I have two equation, u just have to solve it simultaneously
A = 5B ( equation 1)
A+ B = 108 (equation 2)
From equation 2
A+B = 108
B = 108 - A ( equation 3)
Now ill put equation 3 into equation one
A = 5B
A = 5 (108 - A)
A = 540 - 5A
6A = 540
A = 90
Now since u know A = 90, just choose any of the equations the question gave u, either equation 1 or 2, they will give u the same answers, I'll prove it to u
Equation 1
A =5B
90 = 5B
B = 90/5
= 18
Equation 2
A+B = 108
90 + B = 108
B = 108 - 90
= 18
So at the end, A = 90 ton, B = 18 ton
