The simplified expression is: -14s⁴-2s²+3s-3.
First group all the like terms together.
(-8s⁴)+(-6s⁴)=-14s
-2s
7s+(-4s)=3s
-3
Then put the expression back together, starting with the term that has the largest exponent, then working your way down. You would then get: -14s⁴-2s²+3s-3.
3x - 2y = 18
Wherever the line crosses the
x-axis, y=0. 3x = 18
x = 6
The x-intercept is (6, 0) .
3x - 2y = 18
Wherever the line crosses the
y-axis, x=0. - 2y = 18
y = -9
The y-intercept is (0, -9) .
Hello,
(10-4x²)-(7x+?)=3x-6x²
==>10-4x²-7x-3x+6x²=?
==>?=2x²-10x+10
Answer:
The numbers are 14 and 25
Step-by-step explanation:
Let one of the numbers be x. The second number we are told is 3 less than twice x. The second number will thus be;
2x - 3
The sum of the numbers is thus;
x + (2x - 3) = 3x - 3
But the sum of the numbers is said to be 39, therefore;
3x - 3 = 39
3x = 42
x = 14
The second number is thus;
2(14) - 3 = 28 - 3 = 25
9y+7 + 7y-19 = 180
Y =12 degrees
