Answer:
n = -101/90
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
(1+9n) (10) = −91
(1) (10) + (9n) (10) = −91 (Distribute)
10 + 90n = −91
90n + 10 = −91
Step 2: Subtract 10 from both sides.
90n + 10 − 10 = −91 − 10
90n = −101
Step 3: Divide both sides by 90.
90n/90 = −101/90
n = −101/90
7: has a value of 7 hundreds (or 700)
5: has a value of 5 tens (or 50)

I believe you would draw this by drawing something that looks like place value blocks. I have attached an example of that. In the ones column, you will have 6 single blocks
Answer:
18 units²
Step-by-step explanation:
Solve for height:
4² + x² = 5²
16 + x² = 25
9 = x²
x = 3
Solve for area:
Formula = (base1+base2)h / 2
(4 + 8)* 3 ÷ 2
12 * 3 ÷ 2
36 / 2 = 18
