1. 7x(x + 3)
7x(x) + 7(3)
7x² + 21
2. (7x + 1)(x + 3)
7x² + 21x + x + 3
7x² + 22x + 3
3. (x² + x)²
(x² + x)(x² + x)
x^4 + x³ + x³ + x²
x^4 + 2x³ + x²
Answer:
The answer is D.
Step-by-step explanation:
Since there is a triangle with angles A, D, and G. Another congruent triangle has angles B, C, and E. This means that angle E is congruent to angle G.
Answer:
The answer is A
Step-by-step explanation:
Answer:
The answer would be 6.
Step-by-step explanation:
First, we need to make equations for these electricians fee's.
Electrician one: Y=25x+50, 50 is the upfront cost and 25 is the cost per hour for work.
Electrician two: Y=27.50x+35, It is the same thing for these numbers.
Then you need to incert numbers into the X place. Y will be your answer.
Y=25(6)+50, Y=150+50, Y=200
Y=27.50(6)=35, Y=165+35, Y=200
The answer would be 6. If both the electricians worked for 6 hours each, their prices would be equal.
