Answer:
140
Step-by-step explanation:
Substitute q = 5 and u = 7 into the expression
4qu
= 4 × 5 × 7 = 20 × 7 = 140
First, we need to find the slope:
m=rise/run OR
m=(2+2)/(-6-2)
m=4/-8
m=-1/2
second we need to find the equation for the line using point-slope form:
y-(-2)=-(1/2)(x-2)
to find "a" we plug in the given y value and solve for x (in this case x=a):
so, a=6 and the point becomes (6,-4)

Answer:
A. 70°
Step-by-step explanation:
There are two ways to solve this problem:
(1) The sum of all the angles of a quadrilateral equals 360°.
The equation for this problem would be:
110° + 110° + 70° + m∠A = 360°
Simplify:
290° + m∠A = 360°
m∠A = 70°
(2) Trapezoid ABCD is an isosceles trapezoid, because m∠B and m∠C, opposite angles of the same base of the trapezoid, are congruent.
Therefore m∠A and m∠D must also be congruent.
m∠A = m∠D = 70°
You want to use the Pythagorean Theorem: a squared+b squared=c squared
