Answer:
It is 
(12 × 4) = 24
Step-by-step explanation:
(base × height) = area of triangle
(12 × 4) = area
area = 24
Answer:
The area can be found by multiplying the two terms, and the perimeter by doubling and adding them.
Using this, we find that the area of the rectangle is 60x³, and the perimeter is 10x² + 24x.
Step-by-step explanation:
First let's find the area:
5x² × 12x
= 60x³
Now the perimeter:
2(5x² + 12x)
= 10x² + 24x
Answer:
3 bob's burger= 23.67
2 starry night= 17.98
4 clear= 42
Step-by-step explanation:
3 x 7.89= 23.67

Answer: 8
Area of a triangle=(1/2)bh
16=(1/2)4x
16=2x
x=8
Answer:
x = -6 x=5
Step-by-step explanation:
x^2 +x -30 =0
Factor
What two numbers multiply to -30 and add to 1
6 * -5 = -30
6-5 =1
(x+6) (x-5) =0
Using the zero product property
x+6 =0 x-5=0
x+6-6=0-6 x-5+5=0+5
x = -6 x=5
