Evaluate. 4.3 + 2.75 A. 2.78 B. 3.18 C. 7.05 D. 7.5

1 answer:

5 0

1. Set up the long addition.
4.30 + 2.75
2. Calculate 0 + 5, which is 5.
4.30 + 2.75 = 5
3. Calculate 3 + 7, which is 10.
since 10 is two-digit, we carry the first digit 1 to the next column
1
4.30 + 2.75 = 05
1
4.30 + 2.75 = 7.05
5. Therefore, 4.3 + 2.75 = 7.05.
7.05

Factor completely. a 2 + 28a + 27 (a + 1)(a + 27) (a + 3)(a + 9) (a - 1)(a - 27)

8090 [49]

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 $Ax^2+Bx+C$ multiply A*C then find two numbers which multiply to this number and add to B. When you find those numbers, write them as $(x-/+ number)(x-/+number)$ .

$a^2+28a+27$

A=1, C=27

A*C=27 and add to B=28 which 1 and 27 satisfy

The factors are (a+1)(a+27)

Hey! This is a maximum because that's where it peaks. It doesn't go any higher from there so the coordinates are (0,-1) or A.

Find M<1 A. 43 B. 69 C. 137 D. 180

Marina86 [1]

Answer:
137°

Explanation:
In any triangle, the measure of the exterior angle is equal to the summation of the measures of the other two non-adjacent angles.

In the given triangle:
Angle 1 is an exterior angle.
The measures of the non-adjacent angles are 103° and 34°

Based on the above theorem:
measure angle 1 = 103 + 34 = 137°

Hope this helps :)
