7 is the GCF of 21 and 49. Does this help at all?
Internal measure of a triangle is 180 degrees
base angles of an isosceles triangle are =
therefore each base angle is 4x
4x+4x+x=180
9x= 180
x=20
vertex angle= 20
Answer:
33 miles
Step-by-step explanation:
5.5÷4= 1.375 gal per round
1.375×24= 33 miles
If 2 + 3i is a zero, then 2 - 3i is also a zero
x(x - 2 - 3i)(x - 2 + 3i)
= x(x² - 2x + 3ix - 2x + 4 - 6i - 3ix + 6i - 9i²
= x(x² - 4x + 4 + 9)
= x(x² - 4x + 13)
= x³ - 4x² + 13x
