Hi!
I've included an image showing the shape divided into 3 rectangles. We're going to find the area of each rectangle.To find the area of a rectangle,
multiply the length times the width. The red rectangle:8 · 9 = 72
The area of the red rectangle is 72in.
The orange rectangles:The orange rectangles have the same area.
10 · 3 = 30
30 + 30 = 60
The area of both orange rectangles is 60in.
72 + 60 = 132
The answer is
132 square inches.Hope this helps! :)
Answer:
4,037
Step-by-step explanation:
m:w:c = 15:8:11
as there are 2,569 more men than woman we find the difference in the ratio=
15-8 = 7
2,569/7 = 367
this means one part equals 367 people
1:367
as there are 11 children we multiply
11 x 367 = 4037 children
13^2 + 2 * 13 * n + n^2 = 18^2
169 + 26n + n^2 = 324
26n + n^2 = 324 - 169
26n + n^2 = 155
n^2 + 26n - 155 = 0
(n - 5)(n + 31) = 0
n - 5 = 0
n = 5
n + 31 = 0
n = -31.....not this one because it is negative
so n = 5 <===
The dimensions of the box are
y by
y+6 by
y-1.
Answer:
Option B, -4 and 4
Step-by-step explanation:
<u>Step 1: Subtract 15 from both sides</u>
y^2 - 1 - 15 = 15 - 15
<em>y^2 - 16 = 0</em>
<em />
<u>Step 2: Factor</u>
y^2 - 16
<em>(y + 4)(y - 4)</em>
<em />
<u>Step 3: Find the solutions</u>
y + 4 - 4 = 0 - 4 and y - 4 + 4 = 0 + 4
<em>y = -4 and y = 4</em>
<em />
Answer: Option B, -4 and 4
