Answer:
question 19
(2x-5)(3x+1)
Step-by-step explanation:
question 19
6x^2-13x-5
6x^2 coefficient = 6
-13x coeddicient = -13
-5 is constant
multiply coefficient of first term by the constant
i.e. 6*-5= -30
get 2 factors of -30 whoose sum equals -13
-15 +2 = -13
rewrite to have
6x^2-15x+2x-5
3x(2x-5) the firs term
1(2x-5)
add up,
(3x+1)(2x-5)
Answer:
On Sunday they traveled=1/7 of the total distance
Step-by-step explanation:
Total distance to be traveled=x
On Saturday they covered=(5/7)x
Remaining distance=x-(5/7)x=(2/7)x
Sunday=1/2 of the remaining distance=(1/2)×(2/7)x=(1/7)x
On Sunday they traveled=1/7 of the total distance(x)
Answer:
c)11√2
Step-by-step explanation:
Given that two of the angles are equal ,each measuring 45 degrees then two legs will be equal as well each measuring 11 units. We have a right angled triangle with two sides given and we are required to determine the hypotenuse. We use Pythagoras theorem;
hypotenuse^2 = 11^2 + 11^2
hypotenuse ^2 = 242
hypotenuse = 
hypotenuse =
