Answer:
x=11
Step-by-step explanation:
4x+11=5x (angle adb and edf are the same)
11=5x-4x
11=x
if you want you can check by doing...
(14*11-29)+(5*11)=180
X=7
X=2
Since a and 5 aren't like terms, you would write the expression as
(4b^2+3)(4b^2-3)
since it is the expanded form of formula a^2-b^2=(a+b)(a-b) we can write,
=(4b^2)^2-(3)^3
=16b^4-9
y = 4.5x
Explanation:
9 ÷ 2 = 4.5
18 ÷ 4 = 4.5
27 ÷ 6 = 4.5
<em>372₁₀ = 2442₅</em>
<em>372 : 5 = 74 r 2</em>
<em>74 : 5 = 14 r 4</em>
<em>14 : 5 = 2 r 4</em>
<em>2 : 5 = 0 r 2 ↑</em>
<em>write down the remainders in the reverse order</em>
