Evie and her father are comparing their ages. At the current time, Evie's father is 36 years older than her. Theee years from no

artcher [175]

Let F be the father's current age, and E be Evie's current age.
F = E + 36 this is the current relation between the ages
F + 3 = 5(E + 3) this the relationship in 3 year (hence the + 3)
Then solve by substituting one equation into another:
(E + 36) + 3 = 5(E + 3)
E + 39 =  5E + 15
  24 = 4E
  6 = E
Evie's current age is 6.

The first side of a triangle is 3 inches shorter than the second side, and 2 inches longer than the third side. How long is each

ziro4ka [17]

Answer:

the length of the first side of the triangle is $\frac{28}{3}\ in$

the length of the second side of the triangle is $\frac{37}{3}\ in$

the length of the third side of the triangle is $\frac{19}{3}\ in$

Step-by-step explanation:

Let

x-----> the length of the first side of a triangle

y----> the length of the second side of a triangle

z---> the length of the third side of a triangle

we know that

$x=y-3$

$y=x+3$ -----> equation A

$x=z+3$

$z=x-3$ -----> equation B

The perimeter of the triangle is equal to

$P=x+y+z$

$P=28\ in$

so

$28=x+y+z$ -----> equation C

substitute equation A and equation B in equation C

$28=x+(x+3)+(x-3)$

solve for x

$28=3x$

$x=\frac{28}{3}\ in$

Find the value of each side

the first side of a triangle is x

$x=\frac{28}{3}\ in$

the second side of a triangle is y

$y=\frac{28}{3}+3=\frac{37}{3}\ in$

the third side of a triangle is z

$z=\frac{28}{3}-3=\frac{19}{3}\ in$

Solve the quadratic equation by completing the square x^2+5x-3=0

PIT_PIT [208]

${\tt{x = \frac{ -b± \sqrt{ {b}^{2} - 4ac } }{2a} }}$

${\tt{ x = \frac{ - 5±\sqrt{{5}^{2} - 4 \times 1 \times ( - 3)} }{2 \times 1} }}$

${\tt{x = \frac{ - 5±\sqrt{25 + 12} }{2} }}$

${\tt{x = \frac{ - 5 ±\sqrt{37} }{2} }}$

$\: \:$

${\tt{x = \frac{ - 5 + \sqrt{37} }{2} }}$

${\tt{x = \frac{ - 5 - \sqrt{37} }{2} }}$

he knows that the length is 10 feet more than the width, and the total area is 144 feet. Find the dimensions of in feet of Javon

finlep [7]

Answer:

A) length = width +10

B) length * width = 144 OR

B) width = 144 /length putting B) into A)

A) length = 144 / length + 10 then solving for length

A) length^2 = 144 +10 length

A) length^2 -10 length - 144 = 0 then we factor

(length -18) * (length +8) = 0

length = 18 feet

width = 8 feet
