The side of the triangle is 13 inches
Side of square. 6 inches
X= side of square
4x+15 =3(x+7)
4x+15=3x+21
x=6
6+7= 13
Perím square 6x4= 24
Perim triangle 13x3=39
39-24=15
Answer:
C is correct
Step-by-step explanation:
To factor:
4x^2 + 12x + 5
(4x^2 + 2x)(10x + 5)
2x(2x + 1) + 5(2x + 1)
Then, take the outside numbers make them their own group:
2x + 5
(2x + 5)(2x + 1)
Therefore, it’s (2x + 1)(2x + 5)
Answer:
Step-by-step explanation:
We can use the FOIL method to expand two multiplied binomials. It states that . The FOIL method stands for First(first terms) outer(outer terms) inner(inner terms) last(last terms).
So, we can expand our binomials now!
