Answer:

A. 90°+m∠4

Step-by-step explanation:

Also

∠ A + ∠ C = 180 o = ∠ B + ∠ D

⇒ 2 x+ ( 3 x − 5 ) = 180 0 = ( x + 5 ) + ∠ C

5 x − 5 = 180

Add 5 to both sides

5 x = 185

Divide both sides by 5

x = 185 5 = 37

But it was A. 90°+m∠4

Identify the solutions to the quadratic equation!

Elenna [48]

The solution to the quadratic equation are option C) x= -5 and option E) x=3.

Step-by-step explanation:

The given quadratic equation is x²+2x-15 = 0.

Using the factorization method,

product of the roots should be -15.
Sum of the roots should be 2.

⇒ -15 = 5 $\times$ -3

⇒ 2 = 5+(-3)

(x+5)(x-3) = 0

Therefore, x = -5 and x = 3

What is standard form?

Katen [24]

Hey there! :)

When teachers ask you for the standard form in math, they are asking you to find the simplest form an equation with variables can be in.

Ax + By = C

Example : put y=2x -3 into standard form.

Subtract 2x from both sides.

-2x + y = -3 —> standard form.

Hope this helped! :)

Find the width of a rectangle 25 feet and the perimeter is 80

lukranit [14]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - a rectangle with length 25 feet and perimeter 80 feet

To calculate - width of the rectangle

We know that ,

$\bold{Perimeter \: of \: rectangle = 2(l + b)} \\$

where b = width / breadth of rectangle

‎ ‎ ‎

substituting the values in the formula stated above ,

$\bold{80 = 2(25 + b)} \\ \\\bold{ \implies \: 25 + b = \cancel \frac{80}{2} } \\ \\ \bold{\implies \: 25 + b = 40 }\\ \\ \bold{\implies \: b = 40 - 25 }\\ \\\bold{ \implies \: b = 15 \: feet}$
