Answer:
x = 5
Step-by-step explanation:
15 - 10 = x
I got 3.825
your equation would be
(2x-1)(x+7)=72
when you distribute youd get
2x^2 +13x -7 =72
move the 72 over giving you
2x^2 +13x -79=0
i used the quadratic formula and the answer would be 3.825 because a negative answer wouldn’t make sense in this situation

Answer:
- Ram -- ₹1200
- Kalpana -- ₹800
Step-by-step explanation:
Their age total is 15+10=25, so Ram will get 15/25 = 0.6 of the total. Kalpana will get the remaining 0.4 of the total.
Ram receives 0.6 × ₹2000 = ₹1200
Kalpana receives 0.4 × ₹2000 = ₹800
Answer:17
Step-by-step explanation:
Answer:
exponent of x is 33
exponent of y is 0
Step-by-step explanation:
you need to combine all powers (exponents) of x, and all exponents of y separately.
remember : x to the power of a divided by x to the power of b is x to the power of (a-b).
when multiplying, the "-" turns into a "+".
so, we have actually for x the exponent calculation :
8 - 14 -(-39) = 8 - 14 + 39 = 33
so, x³³ remains.
and for the y exponents
-26 -(-5) -(-21) = -26 + 5 + 21 = 0
so, all the y expressions eliminate each other and y⁰ remains.
