4x + 10 = -26
-10 -10
4x = -36
Then -36 divided by 4
X= -9 -9 is the answer.
If we call the number "x" then:
x*25%=21
x*25/100=21
x=21*4
x=84
15) factor out cos: cos(x)(sin(x)+1)=0
Now this is true when either cos(x)=0 (x=pi/2 and 3pi/2)
Or when sin(x)=-1 (x=3pi/2)
So it's solutions are pi/2 and 3pi/2
The answer is B. y = 0.75 + 2.25. because i've done this assement.
Answer:
Hey there!
Pythagorean Theorem: a^2+b^2=c^2
16+25=c^2
41=c^2
c=6.4
Let me know if this helps :)
