Answer:
Step-by-step explanation:
Any time a number has a negative exponent that means that the resulting number will be a fraction (ex. 
). Therefore this number is the smallest number.
Anytime a number has an exponent of 0, it will always equal 1
Step-by-step explanation:
A = (1/2)bh ---> h = 2A/b = 2(12 cm^2)/(5 cm) = 4.80 cm
---> x^2 = h^2 + (b/2)^2
= (4.8 cm)^2 + (2.5)^2
= 23.04 cm^2 + 6.25 cm^2
or x = 5.41 cm
Therefore, the perimeter P is
P = 2x + b = 2(5.41 cm) + 5 cm = 15.8 cm
1.) false
2.) true
3.) false
Similar means equal angles and proportional sides
Triangles can be similar by SSS, AA or SAS
<span>the correct equation is
- 4j² + 3j - 28 =0
ax² + bx + c,
a = -4, b=3 c =- 28.
The discriminent D = b² - 4.a.cD = 3² - 4(-4)(-28)D = -439
If D ≥ 0 there are either 2 roots or one double if = 0)if D< 0, there are no real roots (but 2 imaginary roots)Since D < 0, then there is no real roots
The answer there is no real roots</span>
Answer:
Step-by-step explanation:
1) Expand by distributing terms.
2) Simplify 4*3x to 12x.
3) Simplify 4*2y to 8y.
<u>Therefor, the answer is </u><u>12x + 8y.</u>
