Factor completely. a 2 + 28a + 27 (a + 1)(a + 27) (a + 3)(a + 9) (a - 1)(a - 27)
1 answer:
Answer:
(a+1)(a+27)
Step-by-step explanation:
Trinomials are three term algebraic expressions typically featuring variables to exponent powers. To break these trinomials down we factor them using the diamond method or GCF. The diamond method states that for a trinomial multiply A*C then find two numbers which multiply to this number and add to B. When you find those numbers, write them as
.
A=1, C=27
A*C=27 and add to B=28 which 1 and 27 satisfy
The factors are (a+1)(a+27)

Step-by-step explanation:
We have that, the ratio of the corresponding linear measures of two similar cans of vegetables is 2 to 3.
We want to find the area of the larger can, if the smaller can has a surface area of 180 square centimeters.
We know the scale factor is
To find the surface area of the larger can, we multiply the square of the scale factor by 180.
This implies that, the surface area of the larger can is
