Answer:

$90 in^{2}$

Step-by-step explanation:

Base is an equilateral triangle

slant hight= 12 in

side of base= 5 in

so, perimeter of base = 3(5)=15 in

lateral area = 1/2 pl =1/2 (15)(12) in

=90 in²

X2 - 7x + 9 =0 please leave answer in surf form and simplify

777dan777 [17]

Answer:

x = $\frac{7}{2}$ ± $\frac{\sqrt{13} }{2}$

Step-by-step explanation:

Given

x² - 7x + 9 = 0 ( subtract 9 from both sides )

x² - 7x = - 9

Solve using the method of completing the square

add ( half the coefficient of the x- term)² to both sides

x² + 2( - $\frac{7}{2}$ )x + $\frac{49}{4}$ = - 9 +

(x - $\frac{7}{2}$ )² = $\frac{13}{4}$ ( take the square root of both sides )

x - $\frac{7}{2}$ = ± $\sqrt{\frac{13}{4} }$ = ± $\frac{\sqrt{13} }{2}$ ( add

x = $\frac{7}{2}$ ± $\frac{\sqrt{13} }{2}$ = $\frac{7+/-\sqrt{13} }{2}$

I don’t understand this question?

Andrej [43]

Answer:

no, because it has a constant rate of change

Step-by-step explanation:

this is because the x and y change at the same rate. non linear means that they dont change at the same rate.
