84 sq. ft of the wall has to be covered with paint or wallpaper.
Step-by-step explanation:
- Step 1: Find the area of wallpaper to be covered by calculating the area of the wall and subtracting the areas of the window, mirror and fireplace from it. All are rectangular in shape with are given by A = length × width
Area of the wall = 8 × 16 = 128 ft²
Area of the window = 18/12 × 14 = 1.5 × 14 = 21 ft² (since 1 ft = 12 in)
Area of the fireplace = 5 × 3 = 15 ft²
Area of the mirror = 4 × 2 = 8 ft²
- Step 2: Calculate the area to be painted or covered with wallpaper
Area of the wall to be covered with paint or wallpaper = 128 - (21 + 15 + 8)
= 128 - 44
= 84 ft²

a^2+b^2=c^2
10^2+24^2=c^2
100+576=c^2
676=c^2
c=√676
c=√169×4
c=13×2

The answer would be 49 + 42b if you multiply 7*7 and 7*6b
<u>Answer-</u>
<em>The line equation is,</em>
<u>Solution-</u>
The line 
meets x-axis at the point M, i.e M is the x-intercept of this line. At the x-intercept y=0, so
So, coordinate of M is 
The line 
meets y-axis at point N, i.e N is the y-intercept of this line. At the y-intercept x=0, so
So, coordinate of N is 
The line joining M and N can be found out by applying two point formula of straight line,
As it is given that all the coefficients are integers, so multiplying with 3
Answer:
y=3x+4
Step-by-step explanation:
The equation of the straight line that passes through (-3,-5) with slope 3 can be found using
where m=3 is the slope .
We substitute the slope to get:
We substitute the point to find b.
The equation of the straight line is:
