16-
- They have mammary glands.
- Their body is covered with hai.
- Breathing takes place through lungs.
17- Uniform acceleration is a change of equal velocity in equal interval of tine.
Non- Uniform acceleration is a change of unequal velocity in equal interval of time.
18- Three equation of motion:
- v =u+at
- s=ut+1/2at^2
- v^2 = u^2+ 2as

5x-2y=-10
Making y the subject of the formula;
5x+10=2y
2y=5x+10
y=

The slope is 2.5 or five halves

Answer:
A = 437 mm²
Step-by-step explanation:
The general formula for the area of a triangle:
A =
, where 'b' is the measure of the base and 'h' is the measure of the height
Given the dimensions of the triangle in the picture:
A =
= 437 mm²
Answer:
B and D
Step-by-step explanation:
10x^2 -vx [ has the highest power of X as 2 , so it is to degree 2].
6x^2 - 6x + 5[ has the highest power of x as 2; hence it is to degree 2]
