Answer:
C. (x + 8) (x + 7)
Step-by-step explanation:
<em><u>To factor this trinomial, you must split the middle term (15x) into two terms that can be added to get 15x, and multiplied to get 56:</u></em>
<em><u /></em>
<em><u>Group:</u></em>
<em><u /></em>
<em><u>Take out the GCF (Greatest Common Factor):</u></em>
x(x + 7) 8(x + 7)
(x + 8) (x + 7)
Answer:
inches or approximately 5.97 inches
Step-by-step explanation:
Use the cone volume formula: V = 
r²
The diameter is 8 inches, so the radius will be 4 inches.
Plug in the radius and volume, and solve for h
V = r²
100 = (4²)()
100 = 16
Divide each side by 16
=
Cross multiply and solve for h:
4h = 75
h =
So, the cone's height is or approximately 5.97 inches
Write down the two numbers, one under the other, with the decimal points lined up.
Add zeros so the numbers have the same length.
Then subtract normally, remembering to put the decimal point in the answer.
Answer:
x = 81, y = 68 and z = 99
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
z is an exterior angle, thus
z = 63 + 36 = 99
x and z form a straight angle and are supplementary, so
x + z = 180, that is
x + 99 = 180 ( subtract 99 from both sides )
x = 81
The sum of the 3 angles in a triangle = 180°, thus
z + y + 13 = 180, that is
99 + y + 13 = 180
112 + y = 180 ( subtract 112 from both sides )
y = 68
