Answer:
Step-by-step explanation:
remove the parenthesis
5x+10=20
5x+10-10=20-10
5x=10
x=2
Area of rect. = 5 x 7 = 35
area of triangle = 1/2(2)(7) = 7
area of figure = 35 + 7 = 42
answer
42 <span>units²</span>
Answer:
OPTION A
Step-by-step explanation:
AS IF SHE DOUBLES 1 DIMENSION THE VOLUME BECOMES TWICE.
V=L*B*H
IF L IS DOUBLED ..
THEREFORE,NEW VOLUME=
V2=2L*B*H
V2=2 L*B*H
Answer:
<h3>-3</h3>
Step-by-step explanation:
For two parallel lines. their slope are equal
Find the slope of each of the lines
For line A;
m = 0 -y/0+1
mA = -y/1
For line B;
mB = 9 - 3/8 - 6
mB = 6/2
mB = 3
since their slope are equal hence mA = mB
-y/1 = 3
-y = 3
y = -3
Hence the value of y is -3
