Answer:
528 cm²
Step-by-step explanation:
First I would calculate the area of the side rectangles:
20 x 9 = 180 cm²
There are two identical rectangles on both sides so i would x2
180 x 2 = 360 cm²
The area of the middle rectangle:
6 x 20 = 120 cm²
The area of the triangles:
Area of a triangle = (Base x Height)/2
8 x 6 = 48
48 ÷ 2 = 24
There are two identical triangles on the bottom and the top so x2
24 x 2 = 48
Now add all the values up:
360 + 120 + 48 = 528 cm²
I hope this helps!
Answer:
i think its 20 or 9. depending what is on your paper or screen.
These are steps to construct a square.
Step 1:
Use a straightedge to draw line m and label a point on the line as point F.
Draw a line m and label a point F on it.
Step 2:
Construct a line perpendicular to line m through point F. Label a point on this line as point G.
Draw the line FG perpendicular to the line m.
Step 3:
With the compass open to the desired side length of the square, place the compass point on point F and draw an arc on line m and an arc on FG. Label the points of intersection as H and K.
Draw the sides FH and FK of the square.
Step 4:
Without changing the compass width, place the compass point on H and draw an arc in the interior of ∠HFK.
This is the first step to draw the fourth vertex of the square.
Step 5:
Keeping the same compass width, place the compass on point K and draw an arc in the interior of ∠HFK to intersect the previously drawn arc. Label the point of intersection as point J.
Draw the fourth vertex of the square and label it as J.
Step 6:
Use the straightedge to draw JH and JK.
Join JH and JK to complete the square.
Answer:
X=-5
Step-by-step explanation:
√4x+8=x+3
Simplifies to:
2x+8=x+3
Let's solve your equation step-by-step.
2x+8=x+3
Step 1: Subtract x from both sides.
2x+8−x=x+3−x
x+8=3
Step 2: Subtract 8 from both sides.
x+8−8=3−8
x=−5
Answer:
y = x + 4
