The area of a rectangle is the width times the length:
The perimeter is twice the sum of the dimensions:
Answer:
Option D.
Step-by-step explanation:
we know that
Angle -135° is equal to
360°-135°=225°
The angle belong to the III quadrant
225°-180°=45°
sin(45°)=d/1=d
therefore
sin(-135°)=-sin(45°)=d ---> the value is negative
i need help in that answer too. i was just bout to ask this one
Alright because of P.E.M.D.A.S we want to start with the paranthesis but there is nothing we can do so we move on to exponents.
4^2 is 16
16(20-×)-8(x+3)=8 we need to distribute the numbers in front of the paranthesis across both number inside them.
320-16x-8x-24=8
now combine like terms
296-24x=8
now we need to isolate the variable so subtract 296 from both sides.
-24x=-288
now divide both sides by -24
x= 12
