Step-by-step explanation:
100%=>$2,300
45%=>x
x=$2,300×45÷100=$1035
The pay left for other purposes
$2300-$1035=$1265
Or:
100%=>$2,300
55%=>x
x=$2,300×55÷100=$1265.

Answer:
<h2>
x²+7x-2 = 0</h2>
Step-by-step explanation:
The general form of a quadratic equation with roots a and b is expressed as shown;
x²-(sum of root) x + (product of roots) = 0
x² - (a+b)x + ab = 0 ... 1
Given the sum of roots a+b = -7
Product of roots ab = -2
Substituting this values in equation 1 above wil give;
x²-(-7)x+(-2) = 0
x²+7x-2 = 0
The resulting quadratic polynomial is x²+7x-2 = 0
Answer:
b^8
Step-by-step explanation:
(a^m)^n=a^(m*n)
(b^4)^2=b^(4*2)=b^8
