X+y=28----(a)
x-y=4----(b)
(a)-(b)
2y=24
y=24/2=12----(c)
use (c) in (b)
x=4+12=16

All the best

The sum of the two numbers would be 12 and 16. 12+16=28 and 16-12=4

The rectangle below has an area of x^2-16 square meters and a width of x+4 meters.
Basile [38]
X^2-16 is a difference of squares of the form:

(a^2-b^2) which always factors to:

(a+b)(a-b), in this case we have:

(x+4)(x-4), we are told that width is (x+4) so the length is:

(x-4)

Given the line below.
Grace [21]

Answer:

y+2=(x+2)

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

(-2,-2) and (2,2)

substitute the values

m=\frac{2+2}{2+2}=1

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=1\\(x1,y1)=(-2,-2)

substitute

y-(-2)=(1)(x-(-2))

y+2=(x+2)

NEED HELP ASAP!!! 20 POINTS, 5 STAR REVIEW AND BRAINLIEST TO WHOEVER IS FIRST!

Answer:

#1 is 30 degrees

#2 is obtuse

#3 is "No rhombuses are rectangles"

#4 is D

#5 is A

Step-by-step explanation:

For #1, we have an angle vertical to 120 degrees which includes a right angle, so we make an equation:

90+x=120

x=30

So angle x is 30 degrees aka. Option A

For #2, obtuse angles have the sum of the square of the side lengths that are less than the square of the hypotenuse. In this case, 6^2+4^2<9^2 or 50<81

For #3, rhombuses have two pairs of congruent sides but no right angles while rectangles have two pairs of congruent sides but they also have right angles.

For #4, they are similar because one of the triangles is dialated by a scale factor of 1.5.

For #5, just think of turning the triangle on its other side, aka. option A
