70 / 7 56 + 2 <---
10 58
2) Lillian Why Lillian?
Because, Landon Multiplied instead of dividing.
Lillian: Landon:
50 / ([tex]5^{2}[/tex] - 15) x 5 50 / ([tex]5^{2}[/tex] - 15) x 5
50 / (10) - 5 50 / (10) - 5
5 x 5 50 / 50 <---
25 1
3) Pablo Why Pablo?
Because, Pamela didn't follow the L --> R- (Left to Right) -Rule.
Pablo: Pamela:
(12 + [tex]2^{2}[/tex]) / 4 x 5 (12 + [tex]2^{2}[/tex]) / 4 x 5
([tex]14^{2}[/tex]) / 4 x 5 (12 + 4) / 4 x 5 <---

what is 2 X (6+ 2 + 8) -4
Answer:
The correct answer is 32x - 4
Step-by-step explanation:
1) Simplify 6 + 2 to 8.
[tex]2x(8 + 8) - 4[/tex]
2) Simplify 8 + 8 to 16.
[tex]2x \times 16 - 4[/tex]
3) Simplify 2x × 16 to 32x.
[tex]32x - 4[/tex]
Therefor, the answer is 32x - 4.
What is the perimeter and area of the composite figure?
Step-by-step explanation:
▪AB = AC - EF
= 13 cm - 7 cm
= 6 cm
▪BD = CF - DE
= 16 - 8 cm
= 8 cm
BC = EF
perimeter = CF + EF + DE + AD + AB + BC
= 16 + 7 + 8 + 10 + 6 + 7
= 54 cm
Area of triangles = 1/2 × AB × BD
= 1/2 × 6 × 8
= 48/2
= 24 cm²
Area of rectangle = CF × EF
= 16 × 7
= 112 cm²
the total area = 24 + 112
= 136 cm²

Write the equation of the line passing through (2,0) and (0,-5)
Answer:
y=5/2x+2
Step-by-step explanation:
To get the slope,
(-5-0) /(0-2)=-5/-2=5/2
Introduce points (x,y) (0,2) i.e one of the given points ,it should give same answer either way
(0,2)(x,y)
y-2/x-0=5/2
Cross multiplication,2(y-2)=5(x-0)
2y-4=5x-0
2y=5x-0+4
2y=5x +4
Divide both sides by 2 to get
y=5/2x+2.
