Answer:
(x + 10)(x - 7)
Step-by-step explanation:
It is 3 and 10 in some order. The difference is 7 and it is plus, so the larger number is +10 and the smaller one - 3
(x + 10)(x - 3) should be the answer
10x - 3x = 7x
3x+54=180
180-54
126/3
=42 degrees.
42 degrees is you answer :)
16.45 is less than 16.454, Because 16.45 doesnt have a extra # at the end of the #, Add the pretend 0 to 16.45 and compare 0 to 4, And 4 is greater than 0
Let the first brother = x
second brother = x + 2
third brother = x + 4
<span>The product of the first and third boys' ages is 20 more than twice the second boy's age:
x(x+4) = 2(x+2) + 20
x</span>² + 4x = 2x + 4 + 20
x² + 4x - 2x - 24 = 0
x² + 2x - 24 = 0
(x - 4)(x + 6) = 0
x = 4 or -6 (rejected, age cannot be negative)
First brother = 4
Second brother = 4 + 2 = 6
Third brother = 4 + 4 = 8
The three boys are 4, 6, and 8 years old.
