B-BRACKETS
I-INDICES
D-DIVISION
M-MULTIPLICATION
A-ADDITTION
Answer:
b=4, h=5
Step-by-step explanation:b(b+1) divided by 2 is 10, so b(b+1)=20 so b^2 + b =20 so b^2 +b -20=0 which equals (b+5)(b-4), giving us solutions -5 and 4. However, -5 is invalid bc it is negative, so base must be 4 making height 5
This is cross multiplication.
513.74 times x =513.74x
16.26 times 100=1626
Now there is 1626=513.74x
Do 1626 divided by 513.74 which is 3.16502511
Remember to follow PEMDAS (Parenthesis, Exponents (&roots), Multiplication, Division, Addition, Subtraction)
20-3•6+10²+(6+1)•4
First, solve the parenthesis
6 + 1 = 7
20 - 3 x 6 + 10² + 7 x 4
Next, solve the exponent
10² = 10 x 10 = 100
20 - 3 x 6 + 100 + 7 x 4
Next, solve each multiplication. Remember to bring your sign.
-3 x 6 = -18
7 x 4 = 28
20 - 18 + 100 +28
Simplify
(20 - 18) + (100 + 28)
2 + 128
130
130 is your answer
hope this helps
