Answer:

(x+7)(x+2) = 66

x^2+9x+14=66

x^2 + 9x -52 = 0

(x+13)(x-4) = 0

x = 4 bc the other root, -13, can't be used (it would make the dimensions negative values)

Solve the given system of equations <br> 2x+8y=5<br> 24x-4y=-15
oee [108]

The value of x and y is y= 3/4 and x= -1/2

<h3>What is equation?</h3>

An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.

Given equations:

2x+8y=5........(1)

24x-4y=-15...........(2)

Multiply equation (1) by 12, we get

24x + 96y = 60.....(3)

From (2) and (3), we get

-4y-96y= -15-60

-100 y= -75

y= -75/-100

y= 3/4

and 2x+8y=5

2x + 8 (3/4) =5

2x + 6 = 5

2x= -1

x= -1/2

In the equation t = d/6+3 what is the value of t when d =12
likoan [24]
T=d/6+3
1. Fill in: t=12/6+3
2. Remember PEMDAS!! P(parenthesis)E(Exponents)M(multiply)D(divide)A(add)S(subtract)
So, you will divide 12 by 6 first, which equals out to 2.
3. Write your new equation: t=2+3
4. Add 2+3, which equals to 5.

t=5
