Answer:
x = 5
Step-by-step explanation:
a) The third interior angle of this triangle is 180 - 20 x.
The three interior angles must sum up to 180 degrees.
Therefore, 60 + 7x + 5 + 180 - 20x = 180, or
65 + 180 - 13x = 180, or
65 - 13x = 0
Finally, 13x = 65, and so x = 5
You undistribute like
ab+ac=a(b+c) so
2pir^2+2pirh=(2pir)(r)+(2pir)(h)=2pir(r+h)
If you aer talking about a venn diagram, then the circles will overlap because some shapes have polygons with right angles and angles less than right triangles
example: right triangles or trapezoids
yes, they wil overlap
Answer:
D
Step-by-step explanation:
I can’t give a step-by-step explanation but it’s D
In order to divide polynomials using synthetic division, you must be dividing by a linear expression and the leading coefficient (first number) must be a 1. For example, you can use synthetic division to divide by x + 3 or x – 6, but you cannot use synthetic division to divide by x2 + 2 or 3x2 – x + 7. If the leading coefficient is not a 1, then you must divide by the leading coefficient to turn the leading coefficient into a 1. For example, 3x – 1 would becomex minus 1/3 and 2x + 7 would becomex plus 7/2. If synthetic division will not work, then you must use long division.
