Answer:
8
Step-by-step explanation:
31 divided by 4 is 7.75. you cant have 7.75 boards so youd have to round up to 8
14x. 6+2(7x-3) 6+14x-6 6-6=14x 14x is the final answer
Let the middle child be x
youngest child = x - 1
Oldest child = x + 1
(x - 1)^2 = 8(x + 1) + 4
x^2 - 2x + 1 = 8x + 8 + 4
x^2 - 10x - 11 = 0
(x - 11) * (x + 1) = 0
X = - 1 makes no sense. How can a middle child be - 1 years old?
x = 11
The youngest child is 10
The middle child is 11
The oldest child is 12

=====
10^2 = 100
(8*12) + 4
96 + 4 = 100 So the results have been checked.
Answer:
<h2>b) 50in, 48in, 14in</h2>
Step-by-step explanation:
If <em>a ≤ b < c</em><em> </em>form of a right side, then <em>a² + b² = c²</em>
a) 3ft, 6ft, 5ft
3² + 5² = 6²
9 + 25 = 36
34 = 36 <em>FALSE</em>
b) 50in, 48in, 14in
14² + 48² = 50²
196 + 2304 = 2500
2500 = 2500 <em>CORRECT :)</em>
c) 53m, 48m, 24m
24² + 48² = 53²
576 + 2304 = 2809
2880 = 2809 <em>FALSE</em>
d) 8cm, 17cm, 14cm
8² + 14² = 17²
64 + 196 = 289
260 = 289 <em>FALSE</em>
