Can anyone explain this please

3^2 = 3 × 3 = 3 + 3 + 3 = 9

5^2 = 5 × 5 = 5 + 5 + 5 + 5 + 5 = 25

7^2 = 7 × 7 = 7 + 7 + 7 + 7 + 7 + 7 + 7 = 49

If a number has that little 2 above it, just multiply that number by itself.

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
