Your sum is 4 times 10, or 40. We want to end up with 40. Subtract 8 because you added 8 before to work backwards. You get 32. Divide by 16 because the opposite of multiplication is division. You would get 2.
Answer:
D
Step-by-step explanation:
3*(-7)=(-21)
Answer:
16 cm²
Step-by-step explanation:
The figure is a trapezoid with two parallel sides.
The formula for the area is
A = ½(a + b)h
Data:
a = 5 cm
b = 3 cm
h = 4 cm
Calculation:
A = ½(5 + 3) × 4 = ½ × 8 × 4 = 16 cm²
The area of the trapezoid is 16 cm².

Step-by-step explanation:
What is the equation of the line that passes through the point (2,−7)and has a slope of −4
Answer:
3x=10+13x
We simplify the equation to the form, which is simple to understand
3x=10+13x
We move all terms containing x to the left and all other terms to the right.
+3x-13x=+10
We simplify left and right side of the equation.
-10x=+10
We divide both sides of the equation by -10 to get x.
x=-1
