Answer:
m∠3 = 119°
Step-by-step explanation:
All the angles must equal 360° when added together. You have two known angles that are right next to each other. If you add m∠1 and m∠2, 119 + 61, it is equal to 180°. This means that m∠3 and m∠4 must be equal to 180° as well and since there are only two lines, it is safe to assume that opposing angles are the same so m∠1 = m∠3 and m∠2 = m∠4.
Answer:
-7 or 4
Step-by-step explanation:
use foil to get the quadratic equation:
x^2+5x-2x-10=18
x^2+3x-10=18
bring "18" to the left:
x^2+3x-10-18
x^2+3x-28
so what*what= -28
and
what+what=3
factors of -28: -7,4 -4,7 14,-2 -14,2 -28,1 -1,28
factors whose sum is 3: 7,-4
so substitute "7,-4" in place of 3:
x^2+7x-4x-28
2) split it in two groups
group 1) x^2+7x
group 2) -4x-28
x^2+7x has a GCF of "x"
x(x+7)
group 2) -4x-28 has a gcf of "-4"
-4(x+7)
3) (x-4) (x+7)=0
x-4=0
x=4
x+7=0
x=-7
x=4,-7
Hope this helps!
Answer:
x^2+(y-7)^2=25
Step-by-step explanation:
x^2+y^2-14y=-24
x^2+(y-7)^2-49=-24
x^2+(y-7)^2=25
Answer:
A=2πrh+2πr2 this is the formula you'll need to answer your question!
Step-by-step explanation:
so what you'll do is basically just follow the formula above and fill in the numbers where they need to be.
The two numbers you need to fill in is r which is your radius, which in this case would be 6.
And h which is the height which is 9.
So the total formula now would be, A= 2xπ6x9+2xπx6x2
So your answer would be 565.49 cm or 565 pi cm (this depends on how your teacher wants you to write it.)
Hope this helps at all!!
