Answer: B and D
Step-by-step explanation: 40 * 20 = 800 and 40 * 27 = 1,080
Answer: Statement 1 is the same as statement 2
All 90 degrees are right angles and all right angles are 90 degrees
Step-by-step explanation:
1. If the measure of an angle is 90 degrees, then it is a right angle.
2. If an angle is a right angle, then it will measure 90 degrees.
Statement 1 is the same as statement 2
All 90 degrees are right angles and all right angles are 90 degrees
An ' equal to ' can be introduced such that
If 90 degrees = right Angle
Then right angle = 90 degrees
2x² + 5x = -2
or, 2x²+5x+2=0
or,2x²+4x+x+2=0
or,2x(x+2)+1(x+2)=0
or,(x+2)(2x+2)=0
Two values can be found:
(x+2)=0 (2x+1)=0
or,x= - 2 or,2x= -1
or, x= -1/2
Answer:
The first picture and 28.2 square units
Step-by-step explanation:
Equation: A+1/2ps
A = area of the base
p = perimeter of the base
s = slant height
3²+1/2(12)(3.2)=28.2
