Answer:
yes he will pay 26.75
Step-by-step explanation:
25×.07=1.75 25+1.75=26 75
X-y=5
xy=3.36
add y to both sides on first
x=5+y
sub that in other eqation
(5+y)y=3.36
expand
y^2+5y=3.36
minus 3.36 both sides
y^2+5y-3.36=0
use quadratic formula
for
ay^2+by+c=0

for 1y^2+5y-3.36




y=-2.5+/-3.1
y=5.6 or 0.6
sub back
x=y+5
so
x=10.6 or 5.6
the numbers are either 10.6 and 5.6 or 0.6 and 5.6
wait,but 10.6 and 5.6 don't multiply to get 3.36 so that is an extrainiesous answer
answer is 0.6 and 5.6
Answer:
(3x - 7y)(3x + 7y)
Step-by-step explanation:
9x² - 49y² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
here 9x² = (3x)² ⇒ a = 3x and 49y² = (7y) ⇒ b = 7y
9x² - 49y²
= (3x)² - (7y)² = (3x - 7y)(3x + 7y)
The name is a hexagon, and it has 6 vertices. I hope I helps
Exterior angles are the angles that are outside of the triangle or the ones that aren't inside the triangle. So the exterior angles in this figure are 4 and 6.
