For number 19:
"at least 150" means either 150 ≤ ? or ? ≥ 150
plus 3 so +3x
The answer would be 150 ≤ 100 + 3x
Number 20:
A is at -2.5. The inverse is the opposite so 2.5
A. T. S.A =2* AREA OF TRIANGLE +PREIMETER*5.56
VOLUME=AREA OF *LENGTH[ 5.56]
B. T. S. A=πR{R + SLANT HIGHT }
VOLUME=1/3*π*R*HIGHT{ 7 }
volume of a sphere is 3 by 4 by R cube and surface area of a sphere is 4 Pi R Square
A triangle will be produced from the intersection of the vertical plane and pyramid. The correct options are triangles and trapezoid.
<h3>What is a triangle?</h3>
A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry.
Given that a vertical plane passes through a pyramid that has a horizontal base. Therefore, when the vertical plane and the pyramid meets or intersect the two dimensional figure that will be produced when the two intersect is triangle. It can also be trapezoid if the vertical plane does not intersect exactly in mid of the pyramid.
Hence, a triangle or a trapezoid will be produced from the intersection of the vertical plane and pyramid.
