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:
First rectangle: 12 cm by 2 cm
Second rectangle: 8 cm by 3 cm
Step-by-step explanation:
You can examine factor pairs of 24 to see which pairs meet the requirements:
24 = 1×24 = 2×12 = 3×8 = 4×6
Factor pairs (2, 12) and (3, 8) have one factor that differs by 1 and another factor that differs by 4. We can use these numbers to describe the rectangles:
First rectangle: 12 cm by 2 cm
Second rectangle: 8 cm by 3 cm

Answer:
(4, 1)
Step-by-step explanation:
3x+4y=16 /*4
-4x-3y= - 19 /*3
12x + 16y = 64
<u>- 12x - 9y = - 57 </u>
7y = 7
y = 1
3x+4y=16
3x + 4*1 = 16
3x = 16 - 4
3x = 12
x = 4
