We are looking for k in the equation
(x+4)(x+k/4) = x^2+7x+k
The left hand side expands to:
x^2+(4+k/4)x+k = x^2+7x+k
Comparing coefficients for the linear terms, we have the equation
(4+k/4)=7
Solving for k:
16+k=28
k=12
Thus the number to be subtracted is 15-k=15-12=3
CPCTC means the corresponding parts of congruent triangle that are congruent.
So, angle GAE is approximately equal to angle GEA.
Answer:
C and D
Step-by-step explanation:
His new apartment will cost him "10% more" than what he is paying currently.
100% = current rent
10% = the extra amount he will pay for his new apartment
100% + 10% = new rent
100% + 10% = 110%
Now convert the percent into a decimal by moving the % sign two places to the left and make the % sign into a decimal point.
110% = 1.10
500 * 1.10 = 550
So, he will pay a rent of $550 for his new apartment.
