Answer:
Width = 2
Length = 5
Step-by-step explanation:
let A be the area of the rectangle
L be the length of the rectangle
w be the width of the rectangle
<u><em>Formula</em></u>: ‘<u><em>area of a rectangle</em></u>’
A = L × w
…………………………………………………
A = L × w
⇔ 10 = (w + 3) × w
⇔ 10 = w² + 3w
⇔ w² + 3w - 10 = 0
<u><em>Solving the quadratic equation</em></u> w² + 3w - 10 = 0 :
Δ = 3² - 4(1)(-10) = 9 - (-40) = 9 + 40 = 49
then √Δ = 7
-5 is not valid ,because w represents the width
which must be a positive number
Then w = 2
<u><em>Conclusion</em></u>:
Width = 2
Length = 2 + 3 = 5
Answer:
∠XYZ = 37.5
Step-by-step explanation:
IN THE IMAGE ABOVE
Answer:
y=90 degrees
x=51 degrees
Step-by-step explanation:
all right angles are 90 degrees
90+39=129
180-129=51
The formula for that area would be A=1/2xbxh so you would do A=1/2x3.5x3 and that equals 5.25
The given system of equations represent a single line with positive slope. So option C is correct.
<u>SOLUTION:
</u>
Given system of equations are
Now, if we observe, 
multiplying the 
equation with 2 results in 
equation.
which means the two line equations represents the same line.
Now, let us find the slope of line, 
So, the line has a positive slope.
