Increase in the length of one side = 3.8 ft
Step-by-step explanation:
Yossi has garage whose area is 280 ft²
After rebuilt their is increment in area by 50%
New Area = 280 × 150% = 420 ft²
Also we know that Area of Square = (Length) × (Length)
⇒ Length of Newly built garage = √420 = 20.5 ft
and Length of Originally garage = √280 = 16.7 ft
⇒ Increase in the length of one side = 20.5 - 16.7 = 3.8 ft

Complete the statements below that show y = x2 + 2x - 1 being converted to vertex form.
Form a perfect-square trinomial.
y = x2 + 2x +
− 1−
We want to complete the steps to convert the given quadratic equation into vertex form.
Eventually we will get:
y = (x + 1)^2 - 2
Vertex form of a quadratic equation.
For a quadratic equation with the vertex (h, k), the vertex form is:
y = a*(x - h)^2 + k
Here we start with:
y = x^2 + 2x - 1
1) First, we complete the perfect-square trinomial, we need to add and subtract 1 to get that:
y = x^2 + 2x - 1 + 1 - 1
2) Now we rewrite the equation to be able of completing squares:
y = (x^2 + 2x + 1) - 1 - 1
y = (x^2 + 2x + 1) - 2
3) Now we complete squares
y = (x + 1)^2 - 2
And this is the equation in vertex form, where you can see that the vertex is the point (-1, - 2)

Which expression is equivalent to 32−−√−3x2–√+38–√?
Answer:
8
Step-by-step explanation:
The indices question is not properly written. Find the correct expression in the attachment
[tex]-32^{\frac{3}{5} }[/tex] [tex]= (\sqrt[5]{-32})^3[/tex]
for [tex]\sqrt[5]{-32}[/tex]
we need a value to multiply 5 times that will give us -32;
[tex]\sqrt[5]{-32} = -2[/tex]
substitute the answer in the original expression
[tex]= (\sqrt[5]{-32})^3\\= 2^3[/tex]
Evaluate the resulting indices
[tex]2^3 = 8\\[/tex]
Hence the expression [tex]-32^{\frac{3}{5} }[/tex] is equivalent to 8

how do you differentiate linear equation from those equatipn which are not linear?
Answer:
the x
Step-by-step explanation:
Looking at the x in an equation can reveal its shape. A linear graph can look like y=x, y=mx, y=mx+b (m being any number).
When you look at graphs that aren't linear, the x doesn't stand alone in the equation.
Parabolas have a y=x^2 equation. Cubic graphs are y=x^3. They have something attached to the x.
To see all the different kinds of equations and what their graphs look like you can search up "parent functions" and all the basic formulas show up.

Solve for b:
10abc - 2d = 3d
Answer:
b = d/(2ac)
Step-by-step explanation:
10abc - 2d = 3d
Add 2d to each side
10abc - 2d+2d = 3d+2d
10 abc = 5d
Divide each side by 10ac
10 abc/ (10ac) = 5d/10ac
b = d/(2ac)
Kenny had a total of 140 minutes to read, do homework, and play video games.
He spent x minutes reading.
He spent 2(x+5) minutes doing homework
He spent 25 minutes playing video games
How many minutes did Kenny spend reading
Help fast Please
Answer: 35minutes
Step-by-step explanation:
Minutes spent reading = x
Minutes spent doing homework =2(x+5) = 2x + 10
Minutes spent playing video games = 25minutes
Total minutes used = 140 minutes
x + 2x + 10 + 25 = 140
3x + 35 = 140
3x = 140 - 35
3x = 105
x = 105/3
x = 35 minutes

[tex]\frac{11}{8}[/tex]Answer:
55 in by 40 in
Step-by-step explanation:
The perimeter (P) of a rectangle is calculated as
P = 2l + 2w ( l is the length and w the width )
Here l = [tex]\frac{11}{8}[/tex] y and w = y with P = 190
2y + (2 × [tex]\frac{11}{8}[/tex] y ) = 190
2y + [tex]\frac{11}{4}[/tex] y = 190 ( multiply through by 4 to clear the fraction )
8y + 11y = 760 , that is
19y = 760 ( divide both sides by 19 )
y = 40
Thus l = [tex]\frac{11}{8}[/tex] × 40 = 11 × 5 = 55 in and w = 40 in
