Right triangle has one degree = 45 so it's isosceles right triangle.
let y = hypotenuse of small isosceles right triangle 

y^2 = 7^2 + 7^2
y^2 = 49 + 49
y^2 = 98

so 
x^2 = 98 + 98
x^2 = 196
x = 98

answer
x = 98

Three semicircles are placed in a rectangle, as shown below. The width of the 3 rectangle is 15 . Find the area of the shaded re
Leni [432]

Answer:

Step-by-step explanation:

Width of rectangle = 15 cm

width of rectangle is equal to the radius of each semicircle.

radius of each semicircle (r) = 15 cm.

Diameter of each semicircle = 30 cm

Length of rectangle = 3 x 30 = 90 cm.

Area \:  of  \: shaded  \: region \\  = Area \:  of  \: rectangle \\  \:  \:  \:  \:  \:  - 3  \times area \: of \: one \: semicircle \\  = l \times w - 3 \times   \frac{\pi {r}^{2} }{2}  \\  \\  = 90 \times 15 - 3 \times  \frac{3.14 \times  {15}^{2} }{2}  \\  \\  = 1350 - 3 \times  \frac{3.14 \times  225 }{2}   \\  \\   = 1350 - \frac{2119.5}{2}   \\  \\  = 1350 - 1059.75 \\  \\   \purple { \boxed{ \therefore \: Area \:  of  \: shaded  \: region = 290.25 \:  {cm}^{2}}}  \\

Will give brainliest how to solve 3x-4y = 5x+7y
topjm [15]

Answer:

(5x + -4y)(3x + 7y) = 0

Multiply (5x + -4y) * (3x + 7y)

(5x * (3x + 7y) + -4y * (3x + 7y)) = 0

((3x * 5x + 7y * 5x) + -4y * (3x + 7y)) = 0

Reorder the terms:

((35xy + 15x2) + -4y * (3x + 7y)) = 0

((35xy + 15x2) + -4y * (3x + 7y)) = 0

(35xy + 15x2 + (3x * -4y + 7y * -4y)) = 0

(35xy + 15x2 + (-12xy + -28y2)) = 0

Reorder the terms:

(35xy + -12xy + 15x2 + -28y2) = 0

Combine like terms: 35xy + -12xy = 23xy

(23xy + 15x2 + -28y2) = 0

Solving

23xy + 15x2 + -28y2 = 0

Solving for variable 'x'.

Factor a trinomial.

(5x + -4y)(3x + 7y) = 0

Describe how you can use the information in a table showing a linear relationship to find the slope and y-intercept for the equa
maks197457 [2]
If you have a table that tells you the  (x,y) or coordinates on a graph you can take those coordinates and insert them into the equation y=mx=b. this is the equation to find the slope of a line. If you solve for b in the equation you will have the y intercept. the mx would be the slope.
