Answer:
B = ±X
Step-by-step explanation:
A^2 + B^2 = A^2 + X^2
Subtract A^2 from each side
A^2-A^2 + B^2 = A^2-A^2 + X^2
B^2 = X^2
Take the square root of each side
sqrt(B^2) = ±sqrt(X^2)
B = ±X
The discriminant is <span>−<span>8
</span></span>f<span>(x)</span>=−3<span>x2</span>−2x−1
is of the form <span><span>a<span>x2</span>+bx+c</span>
</span>,with <span><span>a=−3</span>
</span>, <span><span>b=−2</span>
</span> and <span>c=−<span>1</span></span>
Answer:
x = 8
Step-by-step explanation:
5(x-2)=30
Distribute
5x- 10 = 30
Add 10 to each side
5x-10+10 = 30+10
5x= 40
Divide by 5
5x/5=40/5
x = 8
For Example 3 :
First blank is cos (theta)
Second blank is sec(theta)
For Example 4 :
First blank is (x^4)/(2) - (3x^2)
Second blank is 0
Third blank is -4
Fourth blank is 0.4286
Hope this helps :)
