Answer:
2xy^2
Step-by-step explanation:
The terms are "like" so can be combined. It might be helpful to think of this as an application of the distributive property.
-3xy^2 +5xy^2 = (-3 +5)xy^2 = 2xy^2
Answer:
Perimeters is 32.44 unit and area is 30 square unit.
Answer:
4)x=15
5)137 degrees
6)supplementary
7)complentary
8)neither
Step-by-step explanation:
4) complementary angles sum = 90
so (3*15+30)
45+30=75
angle 1+angle 2=90
angle 1+75=90
90-75=15
angle1=15
5) angle z is a linear angle which means angle43+anglez=180
180-43=137 degrees
6) supplementary angles =180 degrees
53+127=180
so these angles are supplementary
7) complementary angles =90
56+34=90
so these angles are complementary
8) angles are vertical
HOpe this helps plz vote my answer the brainiest if it does!!!
Answer:
interest earned= 1436.143
the future value of an annuity= 2836.143
Step-by-step explanation:
Given Data:
Interest rate= 4%
time,t = 18 years
Annual payment, P= 1400
At the end of 18 years, final investment A= ?
As per the interest formula for interest
A= P(1+r)t
Putting the values in above equation
= 1400(1+0.04)^18
= 2836.143
Interest earned = A-P
= 2836.143-1400
= 1436.143 !
