Answer:
(x + 5)(3x - 2)
Step-by-step explanation:
Assuming you require the expression factorised.
3x² + 13x - 10
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 10 = - 30 and sum = + 13
The factors are + 15 and - 2
Use these factors to split the x- term
3x² + 15x - 2x - 10 ( factor the first/second and third/fourth terms )
= 3x(x + 5) - 2(x + 5) ← factor out (x + 5) from each term
= (x + 5)(3x - 2) ← in factored form
Answer:
A = 80 m^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh where b is the base length and h is the height
A = 1/2 (16) *10
A = 80 m^2
Answer:
Area is almost the same as surface area. However, surface area is more complicated, and you have to split the object that you are measuring into different parts to get their area before you can find the whole surface area.

Answer: a and b
Step-by-step explanation:
Answer:
C.
Step-by-step explanation:
Perpendicular ⇒ <em><u>So the slope will be the negative reciprocal to this slope</u></em>
Slope = m = 2
Point = (x,y) = (4,-8)
So, x = 4, y = -8
<em>Putting in the slope-intercept form</em>
-8 = (2)(4) + b
b = -8-8
b = -16
<em>Now we'll put it in the slope-intercept form</em>
<u><em>y = 2x-16</em></u>
=> y = 2x-8-8
=> <u><em>y+8 = 2(x-4)</em></u>
