The answer to this question would be 82.5 because the formula for finding the area of a trapezoid is,
A=a+b /2 h,
Put the numbers in place,
A=15+7/2 7.5,
A=82.5

Answer:

135 ft^2

Step-by-step explanation:

7yd = 7*3 feet = 21 feet

$area \: of \: trapezoid \\ = \frac{1}{2} (15 + 21) \times 7.5 \\ = \frac{1}{2} \times 36 \times 7.5 \\ = 18 \times 7.5 \\ = 135 {feet}^{2}$

Does (-15, -691) make the equation y = -51x - 74 true?<br><br><br>

dimulka [17.4K]

Well, we can input both variables to check and see if the numbers hold.

-691 = -51(-15) - 74

-691 = 765-64

-691 = 701

(-15, -691) does not make the equation true.

Solve the quadratic. x^2+8x+3=0

Reil [10]

Factor
find wht 2 numbers add to 8 and multiply to 3
none do

use quadratic formula which can be used when
ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^{2}}-4ac }{2a}$

a=1
b=8
c=3

x= $\frac{-8+/- \sqrt{8^{2}-4(1)(3)} }{2(1)}$
x= $\frac{ -8+/- \sqrt{64-12} }{2}$
x= $\frac{ -8+/- \sqrt{52} }{2}$
x= $\frac{ -8+/- 2 \sqrt{13} }{2}$
x= $-4+/- \sqrt{13}$

x= $-4+ \sqrt{13}$ or x= $-4- \sqrt{13}$
aprox x=-7.60555 or x=-0.394449
