152 ![\text{cm}^2](https://tex.z-dn.net/?f=%5Ctext%7Bcm%7D%5E2)
Step-by-step explanation:
We know that the total surface area of a cuboid is the sum of the surface area of all six of its faces.
We also know that each opposing side has the same surface area. Thus the total surface area is equal to:
(
)
Answer: B
Step-by-step explanation:
1) a.4x² b.-4x³
2) a.2m³n b.5m^8n^4
3) a.2a^-3b³ b.-1/2a²b^-5
4) a.ke b.e³
5) a.4.5c^5d^-1 b.1/5(-c^-5)(-d²)
6) a.64x²y^-6 b.x^15*(-1/8y^6)
7) a.4a²b^6c^-4 b.a^3b^9c^6
8) a.-5v b.5t^5
9) a.w^-3h^-2 b.-w^-3
We know that
if <span>QT is an altitude of triangle QRS
then
</span><span>the measure of angle QTS is equal to 90</span>°
so
6x+36=90-----> 6x=90-36----> x=54/6
x=9
QR=2x-5-----> QR=2*9-5-----> QR=18-5-----> QR=13
the answer is
QR=13
the answer to this question is 1500 millimeters
