FOIL when multiplying two binomials.
First:
√ 3*√ 3= 3
Outer:
√ 3 *2 = 2√3
Inner:
-4*√3= -4√3
Last:
-4*2=-8
Put it together
3+2√3-4√3-8
Simplify
(-2√3)-5
Final answer: (-2√3)-5
1) The y- axis is where x = 0, so the line "y = -1/2x - 3" will cross the y-axis when x = 0. You plug in "x = 0" into the equation, and get y = 0 -3, so y = -3. That means the line " y = -1/2x - 3" will cross the y-axis ar (0, -3)
2) If there are 2 parallel lines, then there is no solution, because the definition of parallel lines is, " 2 lines in the same plane, that never meet." That makes the solution inconsistent.
The y value of I is (5(2) + 3(5))/(3 + 5) = (10 + 15)/8 = 25/8 = 3.125
The surface area of the newly formed right pyramid is multiplied by scale factor 2.
Given that,
Right pyramid,
Edge of the base = 8 cm
Slant height = 25 cm
<h3>What is surface area?</h3>
Surface area is defined as the area of the surface that is uncovered.
Surface area of the right pyramid = 1/2 * edge of the base * slant height
= 1/2 * 8 * 25
= 100 cm²
Now, two dimensions are doubled,
slant height = 50
Edge of the base = 16
New Surface area of right pyramid = 1/2 * edge of the base * slant height
= 1 / 2 * 50 * 16
= 400 cm²
Now, scale factor, the ratio of the surface areas later to the former,
scale factor = 400 / 100
scale factor = 4
Thus, the surface area of the newly formed right pyramid is multiplied by scale factor 2.
