Remark
I think you want us to do both 3 and 4
Three
QR is 4 points going left from the y axis + 2 points going right from the y axis.
QR = 6 units long.
RT is 4 units above the x axis and 3 units below the x axis
RT = 7 units long
TS = 3 units. For this one you just go from T to S. The graph really helps you. You just need to count.
Problem 4
You need to find the area of the combined figure. You could do it as a trapezoid, which might be the easiest way. I'll do that first.
Area = (b1 + b2)*h/2
Givens
B1 = QR = 6
B2 = UT + TS = 6 + 3 = 9
h = RT = 7
Area
Area = (6 + 9)*7/2
Area = 15 * 7 / 2
Area = 52.5
Comment
You could break this up into a rectangle + a triangle
Find the area of QRTU and add the Area of triangle RTS
<em>Area of the rectangle </em>= L * W
L = RT = 7
W = QR = 6
Area = 7 *6 = 42
<em>Area of the triangle</em> = 1/2 * B * H
B = TS = 3
H = RT =7
Area = 1/2 * 3 * 7
Area = 1/2 * 21
Area = 10.5
Total Area = 42 + 10.5 = 52.5 Both answers agree.
3.4(x+1.58)= - 11.288
Step 1: Distribute 3.4 to the numbers inside the parentheses (x+1.58)
3.4x + (3.4×1.58)= - 11.288
3.4x + 5.372 = -11.288
Step 2: Bring 5.372 to the right side by subtracting it to both sides
3.4x + (5.372 - 5.372 ) = (-11.288 - 5.372)
3.4x + (0) = (-16.66)
3.4x = -16.66
Step 3: Isolate x by dividing 3.4 to both sides
x = -4.9

Answer:
16 hours.
Step-by-step explanation:
There is 30 days in a month, if Robin takes 3 hours to mow the lawn and does this four times a month that would be 12 hours, if she takes 1 hour to pull weeds and does this 4 times as well that would be 4. 4+12 would equal 16 hours.
