Please tell me the answer! I'm crying in confusion! :(

Inessa [10]

First, change the fractions to a common denominator, which is 21.

so 3/7 * 3/3 = 9/21

1/3 * 7/7 = 7/21

Add the two together

9/21 + 7/21 = 16/21

Then take 21/21 - 16/21 = 5/21

There is 5/21 of the pizza left.

F(x) = 2x2 + 12x + 1<br> Determine the vertex

Gnom [1K]

Answer:

Step-by-step explanation:

The vertex would be the highest/lowest point so lets factor this first

when we factor we get

2(x^2+6x+8)

2(x+4) (x+2)

Using zero product property we find the 2 x values and x intercepts are

-4 and -2

the middle point of these points is -3

Substitute -3 for x and solve

2(-3+4) (-3+2)

2 * 1 * -1

2*-1

-2

(-3,-2) is the vertex

Find the area of the figure.

nevsk [136]

Answer:

Step-by-step explanation:

Area of the figure is a sum of area of rectangle 4 cm × 7 cm and trapezoid with bases of 19 cm i 7 cm and altitude of 8 cm.

Therefore:

$A=7\cdot4+\dfrac{7+19}2\cdot8=28+26\cdot4=132$
