Lisa's drawing has the following dimensions:
Width=43.5 cm
Length=934 mm
but 1 cm =10 mm
thus
934mm when converted into cm we shall have:
length=93.4 cm
To get the total length of material required to frame the picture, we calculate the perimeter.
P=2(L+W)
P=2(93.4+43.5) cm
P=2(136.9)
P=273.8 cm
The total length of material required will be 273.8 cm
X = -4
the slope is undefined as it only passes through the x-axis on -4.
Answer:
1 neither
2 supplementary
3 supplementary
Step-by-step explanation:
The formula for finding the area of a trapezoid is: sum of bases*height*1/2
By plugging in the information that we already have, we know: (119+65)*height*1/2=5658
184*1/2*height=5658
92*height=5658
height=61.5cm.
Check:
119+65=184
184*61.5=11316
11316*1/2=5658
Answer:
3x + 15 = 3*10 + 15 = 30 + 15 = 45
<u>3x + 15 = 45</u>
Now,
2x + 25 = 2*10 + 25 = 20 + 25 = 45
<u>2x + 25 = 45</u>
Step-by-step explanation:
3x + 15 + 2x + 25 = 90
or, 5x + 40 = 90
or, 5x = 90 - 40
so, 5x = 50
so, x = 50/5 = 10
