The parabola has 2 solutions (when y = 0. So x = -5 and x = -3)
And the discriminant is a positive value. (Since there are 2 solution or roots, that means the discriminant value must be positive)
- if you want to check to make sure it’s a positive value (visually the graph tells you it’s positive) you would find the equation of the curve then plug in the formula b^2-4ac
For the first equation, I put it in y=mx+b form, so y=-3x-9
the second one is x=4
hope i helped
The perimeters of two opposite triangular faces includes all 4 slant edges and 2 of 4 base edges. The other two base edges are half the base perimeter, so the total length of all edges is
.. 2*(27.5 cm) +(1/2)*(30 cm) = 70 cm
A scale factor is a number which scales or multiplies a quantity, e.g a scale factor of two would mean to multiply whatever the value is by two. Since there are no specific values for LMN and OPQ, the scale factor of the two would be 1/1 because they are one quantity with respect to the other.
